VB bringing down a whole dedicated server?

We run an active VB forum, we're hosted on a hivelocity.com dedicated server... The server has been crashing lately and the deeper we dig into the problem, the more it looks like its the Vbulletin script... now, I don't know if its a bug, a plugin, a messed up server configuration or what...

Here are some error messages I get

Is it my rss feeds? I'm at a total lost... Anyone have any idea? Thanks a million in advance!

disable php-suhosin, increase your php memory limit to 256M, and upgrade to the latest PHP.

The word attacker followed by an IP sure got my attention. I washed a couple of them through some IP lookup sites and got they are from Sweden. Could be as simple as too many connections at one time and the system is crashing. Check your traffic logs.

Not unless you're hosting some real shoddy code. The only way PHP can go rogue is through a script that is parsed by the PHP interpreter.
