List,
Here is the message I have gotten from my latest crash, it is finally a full one, usually, there is no trace left in the log:

The process that is listed in the out put belongs to an instance of JBoss 3.2.1 running inside of a VServer, has anyone had similar occurances?
What is it with you people? A user-mode program should in NO WAY WHAT SO EVER crash a kernel, even if it is a vserver patched linux. The problem has to reside inside some part of the kernel. It can be a race condition that only happens when you have alot of processes, memory, io, ... or something totaly different. It might or might not be vserver related.
