The problem could be caused by one of your plugins. For me, I'm running mEAn, metamod and podbot_mm, and I the server is very stable. What I'd do, is start fresh with a bare bones server, and add back the plugins one at a time until the problem reappears, that way you can figure out what is responsible for it. If the problem is caused by a combination of plugins, that's harder to figure out, but you could try adding only one plugin at a time to see if it is a combination thing or not.
