I have a medium size forum forum.facmedicine.com , all addons disabled ( except sitemap and custom node icon - I tried will all addons disabled and the problem persists) , the forum software is using more resources than expected
I have my memory_limit set to 512M at a VPS server with 3GB of ram and I'm getting tons of 'out of memory' errors , I couldn't figure out where is the problem
this is a small part of my server error log

Running a server (database and web and most likely some other damons) with only 512 MB of RAM is simply out of date.

In addition it seems that you use suphp which is also a ressource hog.

This.

Remove suphp. It is not a XenForo issue, it is a suphp issue.... Even php.net has made some subtle comments on their thoughts of suphp I've seen it kill phphBB, vBulletin, IPB, SMF, and even light weight FluxBB seems to come to a crawl with that enabled.
