Can anyone help me figure out both which plugin might be causing this error and how I fix it?
[4405235.617144] Out of memory: kill process 1450 (apache2) score 75568 or a child
[4405235.617155] Killed process 1450 (apache2) vsz:302272kB, anon-rss:4304kB, file-rss:284kB
That’s the last one, but there are hundreds of errors like that before I rebooted…
I’m running WP 3.0.1 on Rackspace Cloud
I figure it has to be something that is either pushing or pulling an RSS feed, so here are the most-likely contenders
AddToAny
FD Feedburner
Feedlist
FT Facepress II (which doesn’t work anyway so I’ll deactivate and save that for another question)
Intense Debate
Postalicious
If there’s a way to figure it out without taking them all down one at a time, I’d appreciate the help. I pull in content from my delicious and posterous feeds and push it out to RSS, so I’d lose a lot of functionality taking them down.
Thanks in advance.
“RSS” stands for “resident set size,” one way to measure the amount of memory used by a process in Linux. It does not refer to RSS feeds. This probably has very little to do with WordPress, and everything to do with the amount of RAM in your box and how much memory Apache is using. I would recommend looking for answers on Server Fault, ie. Apache hanging with MaxClients is reached. You may be trying to spawn more Apache children than memory allows.
I’ve had the same problem, the problem is your server is getting overloaded. I would track down the source of the problem. To resolve this issue I had to increase my server size to 1024MB, optimize apache and setting up caching. W3 Total Cache is an excellent plugin for WP to help reduce server load and works with the RackSpace CDN.
