 Description  « Hide
Unfortunately, sailing sim crossing are getting worse as the calendar rolls on. This JIRA may belong with the sim family with sailing being susceptible to packet loss, network latency, sim time dilations and other classes of lag.
The best REPRO is to just load any 1.18 Viewer, get a sailboat or ride and cross sims. Your tools will certainly show what's happening.
What you will experience is a mix of the evils listed, varying from 500ms to 20000ms in duration with an occasional full crash. The frequency and duration are location related, void sims with many boats being the worst scenario.

=Evils List=
Loss of LSL control, direction and commands.
HUD's detach or lose data.
Avatar's lose attachments
Boat sinks
Boat flys
Boat goes off world
Avatar loses riders
Cannot stop flying (even with flight assist scripts off)
Cannot Stop Flying and go into access denied parcel on occasions throws avatar several meters
Walking into ground

I am confident there will be additional constructive comments from the community.

This is a good description as to what we, a pretty large community in SL, are experiencing in sailing. But the problem of course is much broader. All manner of vehicles experience these same effects and even if you are not in a vehicle it becomes standard pain the butt LITERALLY to detach and reattach attachments that go to never never land or you your you know what.

eugene sodwind added a comment - 27/Jul/07 08:33 AM
This issue is definitely very big - thanks Bri for raising it.
Also, although I have no data to back up what follows, empyrical observation suggests that the chances of sinking/flying whilst crossing a sim boundary increase with the speed of the vehicle. For the record I have experienced this problem with both Mac and Windows viewers.

jacqueline trudeau added a comment - 27/Jul/07 09:49 AM
It is really strange - consider these two scenarios: 1. sub-30 prim tako, my avatar with no prim attachments (other than the tako HUD) 2. 215 prim Trudeau attachable yacht, prim hair, shoes, jewlery - i'm probably carrying around 500-plus prims. What would you think would exhibit the worse effect? it seems to matter not - both are equally as bad in my experience.

jabath steuart added a comment - 01/Aug/07 07:36 AM
A workaround is to use the 'hudlite' or 'hudliter', provided you are experienced enough to use the minimap to gauge wind direction, although these 2-prim HUDs still experience the same effect. And to wear absolutely no other prim or HUD attachments, although obviously this does nothing to mitigate the other problems. In the last week, I have not been able to complete ONE SINGLE LAP of any of the TYC or SYC courses. I used to sail to relax...

Verkin Raven added a comment - 01/Aug/07 02:43 PM
I'll testify that primcount on boat/avatar doesn't matter. Bare 30-prim Tako or 255+25 prim sailboat with a complex HUD and a prim avatar? Both feel the same nasty effects at borders.

I've crossed sim borders in better condition with a 200+ prim boat and a 1200 prim avatar in early 2005 than a bare avvie and Tako these days.


Dan Doyle added a comment - 02/Aug/07 06:16 AM
I will just add here that really for me there seems to be no change since early 05 its just as bad now as it ever was.. and just as before needs to be fixed

hans zinnemann added a comment - 02/Aug/07 09:26 AM
If my taco hud does not loose any of the information on it when I am racing now I am astonished!

Sling Trebuchet added a comment - 04/Aug/07 02:56 PM
I have at times managed to pass through up to 5 or 6 sims without becoming an open-cockpit submarine, although a quick ducking is normal. I do keep an eye on minimap and try to slow at sim boundaries.
Given that I have difficulty crossing without a boat, I'm kinda delighted every time I manage a crossing when on one.

I don't think it's the prim-count. It's just that the sim handover latency generally sucks.

Losing the boat when on a cruise is a real heart-breaker. Where to rezz the boat ???
Perhaps Linden water could permit rezzing by all - but return a newly-rezzed object after 30 seconds (15 seconds?) unless the prims are sat on.

Maybe the constantly changing wind direction is LL's way of "resolving" the problem for sailors. If they program the wind to constantly head you, you can't actually reach the sim boundary.


Torley Linden added a comment - 06/Aug/07 10:39 AM
I'll confirm the above has been a problem for awhile, and thanks for reporting and commenting on it. I'm linking it to an internal issue. It isn't trivial to fix; I'll let our devs know this continues to be a hot issue.

Bri Hasp added a comment - 07/Aug/07 09:25 PM
Thank you Torley for responding... I must reply that your revised 'Title' says it all.

?? (Region crossings are occasionally slow) ??

I was noting that 'slowness' by the speed today flying across several sims before my viewer tossed me into the bit bucket from hell. After a relog, the sail club members were not as polite discussing loss of huds and several other of my evils list.

Maybe a dev or manager will realize our desire to Skype or Fancy cloud is "occasionally" unwanted!

I did note the frequency of evils is reduced when using the Able viewer or the Nicholaz.


Slanty Uriza added a comment - 08/Aug/07 08:47 AM
Torley,

Is this some odd way to say that you guys don't have a clue how to fix it and we whiners have to shut up and try to live with it? It's funny actually, we never encountered hud loss before, until a few months ago. You broke something and now we have to beg to get it fixed. Gawd am I glad you guys don't run a real business like a garage. Sorry Miss, we kinda broke your breaks (stopping is occasionally slow) but we will fix it if you get us enough voters. Plonkers.


Torley Linden added a comment - 13/Aug/07 09:33 AM
More accurately, it's a very complex problem and we'd like to fix it but it's sadly not so easy too – a "band-aid" won't do. It's personally caused me a lot of pain because I'm often either attachment-laden or in vehicles.

We do welcome Resident efforts to help us fix it.

Also to clarify, votes help tell us "You're affected" and want us to fix it and are one of several criteria. For example, content loss bugs, regardless of votes, need to be fixed ASAP, but votes can help draw attention or help us prioritize one issue above other when there are a multitude of "hot" ones we need to respond to quickly.

Different people have different priorities, after all.


bear plunkett added a comment - 13/Aug/07 01:47 PM
I have had repeated problems with specific sim boundaries, most infuriatingly Tasman – entering both from the west and from the north – in the last 3-4 days

What has been different about these soar-into-the-air-then-underground episodes, lately, is that when I regain some measure of control over my avatar, the left- and right-arrow keys no longer work. I don't know what the significance is, or if it's boat-related (yet) – but hopefully it will help you

FIX THIS THING SOON!!

Sorry for yelling, but enough, already....


josh viking added a comment - 13/Aug/07 03:11 PM
not being a programmer, i wont have much to offer here. but, it seems to matter how fast the boat is going. when the software is running smoothly ( not laggy) , a boat crosses sim borders without any notice or minimal disturbance when going slower , but at faster speeds it sinks deep. maybe a patch code could be built in at sim borders, or in the boat scripting that would "head fake" the computers into thinking a boat or vehicle was really going slow , even though it actually was going faster , as it approached a boundary.

jacqueline trudeau added a comment - 14/Aug/07 05:57 AM
"Different people have different priorities, after all."

Torley, truer words were never spoken. I am sure bringing voice to SL was also a "very complex problem" and not "trivial" to do. Yet LL decided that was their priority, ignoring the repeated requests from residents to improve grid performance and stabilize content loss as THE #1 priority. Thousands of concerned residents signed http://projectopenletter.com, the gist of which was FIX THE GRID before adding new features that very few are clamoring for. Yes, that even includes your beloved Windlight. Comments here, comments on the blog, comments in the SL forums, comments in 3rd party sites and blogs are wondering just when LL is going to take the priorities of the residents seriously.


Torley Linden added a comment - 20/Aug/07 09:52 AM

@Jacqueline: Understood – so that's why I'm going to debunk inaccuracies right now!

Behind-the-scenes, there are many, many projects in our internal Issue Tracker which aren't shown on the public one, which focus on performance & stability aka "FIX THE GRID". I know more needs to be said about them, and we can sure do a better job of communication – so responding, stay tuned for Iridium Linden's message about this in the next Second Opinion newsletter, I am sure all of you interested on what progress we are making on that front won't want to miss it.

One of HetGrid + Message Liberation's (which you may have read on the blog) benefits is that it enables to test new releases with bug fixes (because sometimes there are side effects) on smaller sets of regions, as opposed to the whole Grid. If things go well, then we can scale outwards. We also intend it to mitigate the historical difficulties associated with "I HATE WEDNESDAYS!" downtime, since generally speaking, the whole Grid won't have to be taken offline for server-side upgrades, but it can be done more piecemeal.

We also plan to do upcoming blog posts sharing more about progress on serious issues like inventory loss (which is a priority for many). Again, to EMPHASIZE, there's a lot of work that happens within Linden Lab that we don't trumpet enough, and I'd love to see that continue to change, so for your benefit, you both are aware and can see the effects it has. (IMHO, we need more Lindens to write about what we're doing... otherwise how do you even know, right?)

Also please feel free to check many of my own comments on the Issue Tracker; as someone who spends a lot of time inworld, I empirically feel the brunt of a lot of these pains, so count me in.

ALSO, WindLight itself is a project which includes many bug fixes, such as rendering optimizations to increase viewer performance & stability. That's part of the whole point, after all – it doesn't make any sense whatsoever for this to be an "OR" situation when infact, it's more holistic. As an "AND" context, this carries a priority on addressing longtime problems with our rendering engine that've sucked, and contributed to viewer-side lag.

Here are some examples of WindLight cleanup, more of which will be shared in our release notes:

  • Faster, more reliable occlusion culling - occluded regions are discovered instantaneously, so no more random bad frames due to moving the camera too quickly.
  • No geometry transform overhead on region crossing - results in region crossings being slightly smoother
  • Faster frustum culling - less time spent determining what's visible, thus better overall framerate
  • No copy-to-texture for ripple water - objects under water are rendered to texture at half resolution, resulting in better overall framerate
  • Faster sky updates - the non-WindLight (aka no-shader) skies update quicker

Note the bit about "region crossings", which relates to this issue too. It isn't a big difference, but it is incremental progress we must continue to make. (Also keeping in mind that with beautiful atmospheres, people want smooth vehicle performance – again, they are connected.)

I'll continue to advocate that more Lindens should share what work they're up to, and in the cases where they're too busy actually doing that work, I'll make time to share what I know about it. I wholeheartedly agree that we need to keep driving forward and improving performance & stability (which I sometimes abbreviate as "P&S"), and to that effect, remember we have around 70%, almost 3/4ths, of our devs involved on issues that directly contribute to those efforts, across a broad range of projects.

We don't need false dichotomies – what we need is better followup, and I'm all too happy to share your actionable concerns with other Lindens, because we – and I certainly can say this personally – want your experience to be a happy one.

"We also plan to do upcoming blog posts sharing more about progress on serious issues like inventory loss (which is a priority for many)."

That would be a good start, Torley. The only thing remotely addressing these issues in the blog lately has been a grid or server monkey's (LL's terms of endearment, not mine) notification that some operational procedure was performed to relieve that day's outage.

But excuse us if we take a lot of pronouncements from LL with a healthy grain of sand. We've been enticed with a lot of other things that we've never heard about again.

For instance:
havok 2
Mono
HTML on a prim
SL v2 (which seemed to just lead to a redoing of the SL number versioning)

I have to just shake my head as I read through a transcript such as this:

http://www.slhistory.org/index.php/Town_Hall_4/27/05

I'm all for new features that fix bugs or improve performance, but what issues will be introduced? Unfortunately SL performance has gone steadily downhill since I joined in 2005. I would gladly GLADLY trade the performance we had pre v1.7 for the features we have now.


Torley Linden added a comment - 29/Aug/07 12:51 PM
We are currently working on creating comprehensive teleport and region crossing failure metrics, part of a bigger project to improve both teleports and region crossing reliability (as they are closely related). This will give us better insight into weak points so we can improve them.

jacqueline trudeau added a comment - 30/Aug/07 06:53 PM
Thanks for the update, Torley

cottel andree added a comment - 03/Sep/07 02:29 AM

I just wish to add my voice to the repeated requests to make sim crossings smoother. Sailing in sl is a high priority for me and many other sl residents. The gradual deterioration in this characteristic over the last few months has really created a lot of frustration and disillusionment with sl. Please could you priorities this over putting more bells and whistles into sl. I am sure you have heard the cry to fix the grid instead of adding to it over and over again. So - how about it ?

We all know how wonderful sl can be right now - with no further "improvements" - when it works


Bri Hasp added a comment - 05/Sep/07 05:43 AM
I have observed over the years in visual chats and my tine in Second Life that it boils down to which resident is satisfied. The Active Resident or the Passive Resident.

The Passive Resident only needs a spot to sit and the features are paraded by. Eye Candy and chat pizzazz offered up. Windlight and Voice are classic passive enhancements.

The Active Resident requires a lot more. Participation and more complex objects to hold physics etc..

Business decisions, expansion and the hardware capability favor the Passive resident growth. That futures the server into a basic repository only storing files for the client and doesn't require complex interaction directly with the webserver itself.

I am trying to recall the last enhancement targeted to the Active Resident.

flying and have water up to Linden Protectet water,.
and it is werry bad to cross around the area aroun

Hollys Chevalier added a comment - 22/Sep/07 04:09 PM
Torley's sure right about one thing in particular. This will be a complex issue to resolve.

Lyssa Varun added a comment - 23/Sep/07 12:59 PM
The issue also continues to become more complex as heads are buried in the sand and the problem ignored because it's difficult in favor of sexy new features that then also contribute further to the problem. This is so not just sailing. In fact sailing and other slow moving vehicles are almost the only things we can use anymore it's gotten so bad. Please do something about this!

Pyrii Akula added a comment - 30/Sep/07 06:31 PM
This issue was meant to be fixed many many months ago with server tech which meant the next sim was connected to before crossing, and it shows as we can get terrain data s we get closer and also avatar/prim data. But trying to cross into those sims just times out. Something tells me this is down to the recent slowdown in inter-sim communication. Sim crossings often timeout and thus you're left seemingly flying/walking forever intot he non-existant horizon, which can be very disconcerting, even creepy and scary for some people.

For an issue that was meant to be fixed alreayd, it's strange it has cropped up again and LL's weak response to fixing what seems to be a major bug, when you have 1000s of sims and going between each one is so troublesome.

Failed/slow sim crossings are getting all too frequent, I think they're even above the 50% mark in my recent experience.

As the Cannot Stop Flying Issue has been interpreted as only affecting the original poster, and resolved because the original poster says it does not appear to be such a problem of late, I am transferring the Cannot Stop Flying at Region Crossing issue to here, and have updated the Description accordingly.

Valentine Janus added a comment - 05/Oct/07 02:49 PM
It's not just sailing, and not just size, and not just speed. It breaks pennyfarthings and aircraft with equal impunity. Crossing between sims is the most dangerous thing I do in SL most of the time. I'm working on an inter-sim transit system for two estates, and it's simply not possible to get there under present conditions.

Cruiser Gilman added a comment - 29/Oct/07 05:28 PM
I am an old avatar (3 1/2 years on SL!). I have watched the Sim Crossing throughut this period and am APPALLED at SL's lack of apparent interest. Folks, this is a VERY noticable issue....involving many of us DAILY!! I am a sailor and pilot in real life and remember when flying and sailing were enjoyable.....well before all of the 'modern' add ons appeared (voice, etc). PLEASE revisit this issue and make it a priority.

Haravikk Mistral added a comment - 01/Nov/07 03:36 AM
Linked: VWR-864 = While this is not strictly a viewer issue, it is a big (and very popular!) performance related issue
Linked: SVC-280 = Not a magic bullet fix by any stretch of the imagination, but it should reduce the amount of data that requires sending when an avatar is passed over to another simulator. Likewise it provides an example that could perhaps be used to improve other chunks of avatar data to reduce message size.

HyBosch Otsuzum added a comment - 04/Nov/07 06:54 PM
Agreed. I've been in SL for over a year. My sense is that Sim Crossing has gotten much worse, even while simply walking or flying.

Haravikk Mistral added a comment - 05/Nov/07 03:13 AM
Just read Lyssa's comment and I agree. This has been allowed to get a lot worse by being ignored, region crossings started getting worse and worse so long ago I can't even remember which version(s) introduced changes to region crossing performance. This is a big problem as the changes that caused the huge delays in crossing are now so far back that undoing them will likely be impossible, if they're even known anymore!

The changes that caused these issues should have been reversed or fixed when they happened, yet resident complaints of border crossing issues seems to keep being ignored when they are raised =(


Iexo Bethune added a comment - 16/Nov/07 01:58 AM
I must say, Bri's descriptions of region crossings are gentle compared to some of my more memorable experiences.

I've flown or sailed across the continents a grand total of 3 times for both. During all three times, several times I've flown off into oblivion, eventually losing my vehicle, then myself, then going into partial lockup, where the world no longer exsists, but the viewer's buttons and such continue to function.

There have also been problems with large vehicles, which is to say, vehicles approaching the max link distance, both physical and non-physical, coming unlinked over borders, causing the pilot seat to fly out of the vehicle, and leave a big floating mess behind to clean up with non-phys, and causing a theatrical explosion of prims with physical vehicles, leaving an even harder mess to clean up, as some parts can land a sim or two away. This is a major problem with my TIE Phantom Cloakfighter(physical), which comes in just below the max link distance, as well as Razi Soyinka's Corellian Gunship(non-physical), which has never crossed more than 5 borders before coming unlinked.

Even better are what happens when you increase the speed a bit. I have a certain vehicle, which appears to have become my first case of missing inventory, as it is not where it should be, or anywhere for that matter. It demonstrates a really interesting border problem, as it's capable of flying so fast that it actually goes offworld on region crossings, gets returned to your inventory, and leaves you flowing there, the world frozen, but the viewer still fully operable, as was mentioned before.

This is probably THE reason that nobody buys vehicles. There are oh so many reasons, from all the no-enter parcels to those aggressive, borderline illegal Home Security Orbs, but this is by far the most common, and one of the most destructive problems vehicles have, and it's a very good chance if it were fixed, vehicles would sell infinately better.


Iexo Bethune added a comment - 16/Nov/07 02:33 AM
Ah yes, that reminds me, another set of issues, can better remedies be devised for failed vehicle crossings into restricted or full parcels than being ejected from your vehicle and watching it fly on without you (in the case of restricted parcels), or having your vehicle returned to your inventory, being tossed back across the border, then having your controls locked requiring a restart (in the case of full parcels)?

PS. I found the original vehicle box buried somewhere with a fresh copy of the vehicle inside. The crashingly fast ship is the R-Type FX2 Shrike. Very pretty, wish it was mod. I could apply lots of neat effects now...


Aquarius Paravane added a comment - 16/Nov/07 12:39 PM
The title "Region Crossings are occasionally slow" just does not do justice to this collection of issues.

Some of them are not occasional, they always happen; and if it was just a bit of slowness it would be less problematic than the following (to summarize):

1) When I am crossing a region boundary in a vehicle, my vehicle should not
a) disappear forever (especially if it's no-copy)
b) dip underwater or underground
c) fly or sail under land or water through negative coordinates uncontrollably followed by a viewer freeze or crash
d) unlink.

2) When I am crossing a region boundary with or without a vehicle I do not want
a) my hair and shoes to detach from their proper locations or
b) re-attach to the center of my avatar

3) When travelling in a vehicle, and encountering parcel full or land with no object entry permissions, I do not want
a) my vehicle to unseat me or
b) be returned to my inventory.
What would make sense here would be for the vehicle to be unable to enter the parcel, as if it was a ban line, but that leads to the related issues of
c) I want to see ban lines from greater distance when travelling in a vehicle and
d) I do not want to see ban lines when I am sitting in my house chatting to friends and enjoying the view.

Did I leave anything out?


Siro Mfume added a comment - 19/Nov/07 07:39 AM
This is an issue I have long hoped they would fix. I have walked across sim borders only to lose control of my avatar as it walks off into the distance forever.

I've managed to lose attachments a quarter of a way into a sim. Which might suggest that the inter-sim connectivity needs some looking at, if the latency is that high. Perhaps they need to look at the way avatars are transferred from sim to sim, so that they don't have to send quite as much data when crossing borders.


Graelin Beale added a comment - 01/Dec/07 07:19 PM
I was a fairly avid sailor until last March, because sim crossings were getting to be difficult then.. now they are impossible. I have a good half dozen boats (or more) in my inventory that I don't even bother pulling out to look at let alone use. Lindens need to start paying attention to what their customers want instead of what they feel like working on because it's easier. Fix the broke stuff before adding new (how many manhours were used to create the still-screwy voice system that could have been better put to use in fixing problems that have been with this progam/simulation/game/virtual reality since before I joined up over a year and a half ago?)

Argent Stonecutter added a comment - 04/Dec/07 11:59 AM
I've actually noticed sim crossings have gotten better over the last several months. At one point it got so bad I sold off some land and put up a wall on the sim edge of a parcel because region crossing had too high a chance of logging me off. Flying was impossible, within two or three sim crossings you would ALWAYS lose your plane.

It's not that bad any more. It's still not as good as it was when I started, but it IS improving.


handmadeandroid zenovka added a comment - 06/Jan/08 02:03 AM
I too have seen performance drop since joining just under a year ago. I really enjoy the vehicle side of sl, I like planes, helicopters, cars and boats, yet the most I can manage is flying around or driving in a small circle, border crossings are nearly impossible, which to me at least kind of kills the point of it all.To add to this, it's not like this is a free service we are whining on about is it, it is one most of us pay top dollar for.

TigroSpottystripes Katsu added a comment - 06/Jan/08 07:16 AM
with better hardware, and trying crossing between sims with better performance, latelly I've noticed an smaller rate of mishaps during region crossing, althought I must admit I rarely come out of my parcel.......

Deany Fall added a comment - 16/Feb/08 10:57 AM
Right.. I currently have VERSION 1.8.3.5

now this version is somewhat old

but guess what

I get 0 teleport problems and 0 region crossing problems!

How weird is this?

The only problems I get are.. RARE walking into ground, but it resolves..

Hmm - maybe you should check the 1.8.3.5 code and maybe fix it? - Just a comment to tell you older versions like 1.8.3.5 work FINE! After that version.. it went all in a pickle.

I won't upgrade until It's fixed


Rascal Ratelle added a comment - 04/Mar/08 04:36 AM
ever since the upgrades to 1.19 this issue has been worse.

logs added.


Bunnie Mills added a comment - 17/May/08 08:32 AM
I confirm, after Havok4 the sim crossing got worse, to the point that we hardly ever manage to cross without needing to relog to
fix the consequences.

there are times when this happens even when not using vehicles or attachments.

we're experiencing this in 9 regions which suffer no lag, using both the normal and the beta viewers.
server version is now 1.21.1.87495.

i just hope this can get some priority !


zinbaco kattun added a comment - 27/May/08 12:50 AM
Some boundary crossings are worse than others, we have a group of 10 islands one full the rest openspace. I know which ones I need to go carefully over the boundary and others which are fine, so does this also have something to do with the server the sim is on and maybe other stuff, as well as the code version of server and client.

For a crossing just to be slow would be good, or rather better than what actuall happens which is that you just keep on sliding through then stop, sometimes back to the boudary others just regain control where you are. One inparticular is a nightmare every time without fail - and that is just walking never mind trying to cross it in a vehicle - and it would be the one with an underwater tunnel crossing the boundary so you end up outside of the tunnel.


Worren Whitfield added a comment - 27/May/08 12:16 PM
The evolution of virtual environment has seen massive improvements in content and creative medium that approaches the interactive power of a real world environment, all with the notable exception of the sim crossovers. Seamless transition across these artificial borders is absolutely necessary to render the virtual world as plausible, with the same quantum effect on interactivity that virtual building has done for creativity. Sailors in SL are merely the front line in seeing this problem; the general population, as it develops, has begun recognizing that crossovers are unpredictable (and damaging, a times) jolts back to reality. They do not have the smooth mobility to confidently build larger sim clusters and more creative environments. It is the next logical step to correct these crossovers to get the full sense of world, in the virtual world.

Worren


MasterDV Hammerer added a comment - 07/Jun/08 10:12 AM
In addition to the latency issues with sim crossings, crashing into banlines continue to be a problem. It is near to impossible to see a banline when moving on a sailboat, then cross a sim right into a banline. Needless to say, flying into the water and ending up on several plots away and having your boat thrown who-knows-where isn't very realistic.

markbyron falta added a comment - 08/Jun/08 07:11 AM
Updated for current server version and rephrased summary. The problem has apparently worsened with the last server update; even vehicle crossing between two new sims with very low frame time (i.e Elbert to Eyharts) results in a full bork where you fly across multiple sims and the vehilce comes off.

eren padar added a comment - 09/Jun/08 03:30 AM - edited
Please refer to SVC-2377. It is almost a year later, 330+ votes... and this issue is not only unresolved... it is getting worse.

Bunnie Mills added a comment - 14/Jun/08 09:09 AM
something happened. sim crossing is still causing little jerks or short freezing, but got definitely better than the last few months, to the point that i can think of go sailing !
what caused this? not sure whether an update or something else, like a routing optimisation among our regions.

looking forward for further improvements - and stability.

@Bunnie - we're continuing to work on this. We've made a few fixes that knocked down the most frequent failure points, and a big one is yet to come as part of the SVC-972 fix in the next viewer. We're also rolling out some additional diagnostic tools with the next server version which will help us better understand the remaining issues.

Thanks Soft, for several months I had been spending most of my time in one sim and teleporting to other places. Now that I live in the corner of the next sim (Pavonia) I regularly notice it when I cross into the adjoining sims. Actually, used to live across the linden road from there and the change is dramatic! Nothing obvious in the statistics bar so I am guessing it is data transfer/handoff at play.

Not sure if it is related, but teleports started failing much more frequently too!

Arrgh, me pirate ship can't get across a sim to chase treasure without a stumble. And my $4000 custom motorcycle (with me on it) has flown to +100,000, +100,000, +100,000 and farther from SL. I have a Quicktime movie to prove it.

What good are pretty sunsets if I can sail (or ride off) into the sunset?

(Oh, and why does the 1.20 RC perform better than regular viewer 1.20?. I've gone back to the RC.)

This issue has existed since I joined SL in 2006. Over that time, it has swung back and forth between bad and worse. This issue is still in effect. Repro: 1.20 viewer and 1.24.4 server. I understand that this one face of an underlying architecture issue, but between this and the asset issues, it feels like SL is reduced to a very pretty chat client every 3-4 days.

test cases:
104 prim fully linked nonphys vehicle.
21 prim phys vehicle.
Running, with an ARC of 567. (not even in a vehicle!)

Please, LL, show us some of the transparency we love, and give us some kind of status on this issue, as well as the other highly voted ones. From what we see, nothing is really happening with this.

Still broken

a few days some sims (2 full sims, 3 open sims) were joined in the regionmade up by Geometry, Astronomy, Navigation, Tradition. Intention was to make an area fit for sailing. But crossing sim borders at some speed, the avatar is pulled out from the craft.
So the issue still exists.

this is one of the worst bugs in SL

did you mention prims go phantom when crossing? bridges to next sim are nearly impossible to make.

convention centers get jacked up.

DIPPING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

please fix! builders are really suffering with this

I understand that management has finally come up with a solution for this one. As region crossings are a resource intensive operation, a toll will be automatically collected each time you cross a region and the tolls will be adjusted higher depending on how many attachments you have. The highest tolls will be imposed on those using vehicles as these strain the servers to the maximum and result in a reduced user experience. Even as the tolls are imposed, management will be monitoring avatar region crossing and those who use attachments or vehicles with excessively high prim counts or scripts (exact numbers are TBD) or attempting to cross at excessively high speeds (the speed limit TBD) will be given a warning or suspension if warnings are not heeded. This new policy along with the toll revenue will ensure that Linden's very limited technical resources are devoted to improving the virtual meeting space experience for corporate and government customers.

This one isn't even assigned to anyone. Seems the Lindens have given up on getting sim crossings addressed.

Maybe they are waiting for Moore's law to catch up with their imaginations?

Is there anyone out there?

... hello?

This is my BIGGEST gripe..I love flying vehicles, and the situation has only gotten worse it seems.

This "bug" or whatever we choose call it really irks me. We have a virtual world...and yet we cannot travel except by teleporting and bypassing th world itself.

I am EXTREMELY cautious each time I cross a border (no fun flying in just one sim/region; why do it??? it's the travel and seeing all of SL and what people have created that is so cool)...and yet, even with extreme caution (phys or nonphys vehicles) I am crashed every few sims.

I put up with it but absolutely hate it.

Actually, I have heard of other virtual worlds...and will begin checking them out to see if they offer anything better.

Definitely getting worse.

Gordon Wendt added a comment - 17/Dec/08 08:37 PM
Not a showstopper but really this is a critical issue and I can see why everyone (myself included) are starting to get annoyed by this. From being at the meetings I know that it's a complex issue but the fact that there's been little to negative improvement (depending on the day) id disappointing.

I realise LL are busy, and this is probably a complicated architectural change - but, really LL, I mean come on???? I have been in SL since 2004 and vehicle sim-crossings have NOT improved ONE JOT. It's pretty disgraceful. This destroys my immersion and enjoyment of Second Life no end. Please concentrate on stability and reliability, and not on superfluous unneeded features. Thank you.

Response made to josh viking's comments. Would making the boarder wider help? Allowing more time to pass before the AV actually reaches the boarder. A false boarder, so to speak, remotely sensing the AV before it arrives. Very much an I/O speed problem. Reducing mouse sensitivity in preferences does help, some. Being a programmer is a gadget possible inside SL?

Still a problem on April 5 2009

This seems to affect non-physical vehicle region crossings as well.

Once hand-off fails... I can't teleport home or away. I'm sitting in space in a region that doesn't seem to acknowledge that I'm there, requiring a relog. (and often incurring the 5 minute can't-log-back-in penalty).

I usually request region reboots when I notice this happening and it seems to go away for a while after that.


Metric Halfpint added a comment - 21/Apr/09 03:03 PM
To be sure this is indeed another of SL's very sensitive issues and until addressed will continue to be the same.
I have land on 2 adjoining sims and its frustrating to say the least when one can travel west and fall through the cracks yet travel beck east and pass over with little or no problems.
Flying seems to have the least affect with only a minor "twitch'" being noticed most of the time.

It should be given some priority and we (the CUSTOMER) should be kept up to date with on going advice re this problem.
AS one writer (above) astutely typed... 'It's the travel experience to actually see what others have and are doing in the whole place that makes SL a great experience and not just what is on ONE sim."
It needs to be addressed very quickly Linden Labs.. very quickly indeed.

I note with interest that the last notes from any 'Linden' was several months ago even if lindens are not truly involved it would be nice to know that they acknowledge the problem and be the 'Transparent' company they have always said they would be.

Hiding from it doesn't fix it

Wasn't this supposed to get better with the implementation of LLNet instead of worse?

Joyofrlc Acker added a comment - 15/Jun/09 11:06 AM
"This" has definitely been getting worse especially in the last couple of weeks.
Specifically, very slow
Sim border crossings, and various forms of "crashes". IMHO This issue is now getting critical for sailing, and Im sure it must be a problem for the various flyers out there too.

How do we get Lindens to take notice and actually do something. Actually assigning someone to it might be a good start.
Another would be to explain the current deterioration. There must be a cause. Prior to the last couple of weeks Id describe things as poor but almost tolerable. Now its borderline intolerable. Some races less than 50% survive.

Perhaps we all have to just start filing tickets every time theres a problem (and reopening when they fail to answer in a meaningful way).

Failed region crossings has gotten far worse in the last fw weeks. I have an autopilot driven flying ferry system that goes between two full-SIMs approximately once every 10 minutes or on demand. I used to see around 10-15of the ferries in my Lost & fround folder, or about 7% failures in 24 hours. Now I see nearly 100 of them a day. That is nearly a 50% failure rate. Almost all of them are reported as objects that have fallen off the end of the world, but with the coordinates clearly in between the SIMs. Example:

Second Life: Your object 'Faery Ferry (30) - gateway' has been returned to your inventory lost and found folder from parcel 'Gateway to the Faery Crossing' at Wildefleur 124, 257 because it went off-world.
Second Life: Your object 'Faery Ferry (30) - gateway' has been returned to your inventory lost and found folder from parcel 'Bluebonnet Gleann' at The Faery Crossing -1, 128 because it went off-world.

Additional failures occur with great regularity. I now find vehicles stuck just past a region crossing point no longer physical. Manually settting the vehicle back to physical awakens it to go to its destination. Region crossings are now routinely causing loss of the physical attribute. Now I can work around this problem by haveing a changed_region event kick a timer to keep seting the the physical attribute for several seconds, but I believe the Lindens should investigate why crossings have gotten much worse lately.
