Hey, I've been running into some odd issues that I haven't been able to figure out yet. Apache2 processes are hanging while trying to lock a php session file. They keep hanging until my MaxClients limit is hit, and then the server stops responding to any HTTP requests

I noticed this on one server, and I ran into my MaxClients limit on another server a couple days later. One server has a pile of proxies - the other just has one. I'm not sure what's going on, but wanted to see if anyone else was having issues.
