There was also this thread on ther freebsd-database list a while back. http://www.daemonnews.org/mailinglists/FreeBSD/freebsd-database/msg01178.ht= ml couldn't search through the actual freebsd site for some reason but google found it. There the author said dropping back down to 4.11 seemed to solve the problem. I am running a MySQL 5 server on a dual, dualcore amd 64 system with a max queries persecond i think we hit was in the 200 - 300 range. If I remember back to the conversations then, I think the problem started to surface at about 500 or so queries persecond. I haven't had any problems with MySQL 5 and I really think its worth the step up. It seems some people at MySQL looked into the problem for that thread I linked to but i don't know if any type of solution was found on the MySQL side. It just seems the 4.x doesn't like the high loads on FreeBSD for some reason.
