Linden Lab Issue ID: SL-56680


 Description  « Hide
The forums seem to be running very slowly, and giving out 503 errors at random.

However, this seems to only happen at peak times.
NOTE: back in March this was only during peak times, now it appears to be nearly constant.
Have seen:
503 errors
Error messages from web cache system
Errors stating that a database access has failed

Very repeatable at this writing (9/28/07; 8 am)

There are also sporadic but common 503 errors all over the SL web site.

I've seen this myself, sporadically and intermittently. I think it has to do with our load balancing. If you notice a period of time where it sustains for at least several minutes (and I've known it to affect various pages on secondlife.com), please post the precise time, date, and duration here.

This isn't enough info to reproduce the problem; please provide more info or close the bug.

The forums are currently unusable due to errors on 50% or more of the hits.

This condition first became noticable the evening of the 28th (Pacific time), and has been steadily worsening.

This actually started on the 26th for me, but it's been very, VERY bad this morning (28th)...closer to 75%.

Note the original issue is from back in March.. Maybe a different cause this time but the forums are definitely hurting.

Lindal Kidd added a comment - 28/Sep/07 11:07 AM
Also 505 errors, "the service is not available".

Still seeing this about 20-50 per cent of the time while navigating the forums, although it has improved since this morning (9/28).

As of 16:23 SLT this seems to be very slowly improving. Forum and website pages are slow to load and give inconsistent results. Error 503 is my most commonly received error and is still occurring.

Actually Nika, I noticed it on the 26th. I've also submitted a support ticket regarding transaction histories not downloading correctly since the 17th. On the 26th of September, the entire area of southern AZ lost internet connectivity for 8 hours on one cable carrier. I thought the 503 errors were a result of this, but have continued through the restored connectivity.

503 Error seems to be gone. Now I'm getting a URL database error; I've attached a screenshot entitled "URL Error.jpg." This occurs with frustrating regularity in the Forums.

Twosteppin Jewell added a comment - 29/Sep/07 10:31 AM
The 503 error does not seem to be happening any more (at least to me), but I am now getting that URL message (the one Oryx posted) about every 3-4 page requests.

Sally Silvera added a comment - 29/Sep/07 10:39 AM
Exactly the same here. 503s and 404s have gone, now it's constant URL errors. It can take up to four or five attempts to get a page to load.

Sling Trebuchet added a comment - 29/Sep/07 10:54 AM
In many web servers, such errors will show up in the logs.
Many webmasters analyse their logs, looking for problems.
Given the near-constancy of the errors, the error logs are probably ginormous (and a little had to not notice).

However, it could be that the web server software in use by LL is really, really cutting edge, etc - and doesn't log anything, so they don't know when or even if it's happening
Yeah. That's probably it.

Wanted to update: I have not had any of these errors since yesterday evening, however every 3rd-4th forum page seems to take a very very long time to load now. I can usually mitigate that by simply stopping the current load and then reloading, although sometimes even that approach takes 2 or 3 times to work.

Twosteppin Jewell added a comment - 01/Oct/07 03:20 PM
The URL error has returned, although I did manage almost 48 hours without it. I am not getting it as often as I was on Friday and early Saturday, but it is back - intermixed with the extremely slow page loads.

The offending web server was taken out of rotation. Things should improve!

Dekka Raymaker added a comment - 02/Oct/07 07:54 AM
Had these errors occur on all web site pages, except blog at this time stamp

Gigs Taggart added a comment - 28/Nov/07 06:03 PM
Reopen if you are still getting it.

This has been very common over the past three or four days - I would estimate that I am getting 5-10% 503 responses, which might not sound a lot but which makes it difficult in practice to use the forums. In addition, I have received 503 responses when trying to log in via the latest Windlight.

Also 503 errors on Search All (New) today. Other Search tabs work ok.

Is it possible to change the component? Only my new bug has whole web site as component. adn is is not possible only to access the forums, I cannot access my account page, the events cannot be fetched and so on...

When Accessing web pages, I get HTTP-Errors often or just no data.

  • 503 (Service not available) in about 1/5 or the cases
  • 500 (Internal Server Error)
  • 302 (Moved Temporarely)

Getting the status page (grid is open) instead of the account page repeatedly is not only just annoying, if one needs to access the account page.

When looking into the HTTP-Headers for the event pages, I discovered that listing and the single events come with no cache headers. Means: the browser is forced to refetch event data on every visit. There also is no modified date and time for the page, so that one needs to refetch the page for own listings, even, if the data was not changed. There is no chance to use normal header requests which would prodcve much less server load to see, if something has changed. Expire date is older than the page fetch.

Example:
curl -I http://secondlife.com/events/event.php?id=1173595
HTTP/1.0 200 OK

17:53 PST, didn't count exactly how long it lasted but it took by my count 12 tries spaced out since apparently spamming refresh just seems to make it worse not better. Page I was trying to load was http://forums.secondlife.com/index.php? btw.

It is happening on all pages of the site now. It is very frustrating.

Dina Vanalten added a comment - 05/Feb/08 06:49 AM
503 also happens on in-world search.

Gigs Taggart added a comment - 16/Apr/08 08:27 AM
I can't reproduce this lately, if it's still happening on a regular basis reopen this.
