Getting a lot of 504 - Gateway Timeout

Yeah, I'm getting a lot of this now.

i haven't gotten any actual 504s, but every once in a while the forums will stop responding for a few minutes.

You haven't been hanging out here much, then. :P

I've been hitting 504s out the ass.

I have also been encountering it a lot.

Ramius · December 2007

yeah, me too. I'm not sure the cause, yet. Our load average on the webservers is fine. I don't have management or observational capabilities for the database server, but I would guess that is where we are timing out. That box is shared amongst many parts of the site, and so it is possible there is something going on elsewhere (store, mainsite, adverts, etc) which is affecting us, here.

I haven't hit any timeouts, but sometimes it takes 60 seconds or so to load the next page I try to go to.

Ramius · December 2007

yeah, that would be a "soft" timeout. The 504 gateway timeout is basically the reverse proxy reporting that it has given up waiting for Apache to respond. But you can have a timeout that takes several seconds before the proxy gives up, which eventually results in a successful pageload.

I've also been getting both the "soft" and 504 timeouts a lot this last 2-3 days

I seem to get them every time I try to post. In G&T at least, hopefully this gets through here.

edit- Ah yes, it does about half an hour later. I'm guessing you guys already know how broken the forums were for about an hour there and this would be why it's fixed.

edit- Yikes! Multipost a palooza! Seems they all eventually got through after all.

I got this when making a thread, and the thread is showing up blank. Can't see anything...I can't even report it.

Haven't had a problem for a while now, but just this evening I've had a couple of instances of slow loading, and a 504 Gateway Time-Out. This isn't bitching about problems or anything like that, just checking if it's an issue that's still around/coming back.

Ramius · January 2008

Yeah, it is still with us for a little bit, yet.

I have an archiving system on-deck, but an upcoming family vacation will probably push it back yet another couple weeks. There has also been some discussion of dedicating a slave database for searches (which is the main culprit for the timeouts), and even possibly offloading the searches to a search system instead of relying on MySQL's fulltext index. Because of the nature of these changes, I cannot just drop them into the source code and off we go. All of this work requires some reconfiguration of services on the servers and/or installation of new software. So I need to coordinate the work with the overall server maintenance and growth plans, which makes it a little more time-consuming to come to resolution. But Soon! Within the month of January, I'm quite certain, we should see major (and hopefully long-lasting) performance improvements.

darleysam · January 2008

In time for my birthday? Oh Ramius, you stud.

Aldo · January 2008

So it would help if we'd all use the search function a little less?
