Update;
It seems to be correcting itself again, allthough I made two alterations, I disabled vbulletins live topic and vboptimize, given that the optimize was already built into the configuration of vbulletin (memcached) and using xcache with vbseo , it appears to be "ok" as of this moment, but I'm sure it will go haywire shortly.

please note those lines with "Timeout", I think this may be an important clue. Many lsphp5 process are waiting something and get timeout, this will cause high load. I guess maybe waiting for responses from MySQL. most likely code bug somewhere, cause high load under some conditions.
