I've been having the same kind of problems. Eclipse used to crash once every 10 minutes or so. I then updated Eclipse and disabled one of the major plugins I was using, and that seemed to help somewhat (crashes have been reduced to a handful in a day). I'll try that setting too, and see if I can reduce crashes to zero. What is this PermGen thing anyway? I hadn't even heard about it until I read the workspace log to see what caused the hang/crash.
