Hi All,
We've a JBoss server running and everything works fine. But sometimes, the
JBoss server gets shutdown abruptly with no exception or error message in the
server.log and also i don't see any crash file or any other trace to my
knowledge.
We are using JBoss 4.0.1sp1 with Java 1.5 on Mac OS X.
The number of threads running on that box is around 500 and CPU utilization
seems to be normal. The min and max heap size are 256 and 512 M respectively.
Using top, we don't see any issues with the memory usage though the max heap
size is sometimes as high as 440M. Even if we've any issues with memory usage,
we expect to get some OutOfMemoryError and we ARE NOT seeing this either. We
are not able to reproduce this issue at will.
All the sudden the server silently goes down and we don't see a pattern or
reason that triggers it. But we do see the following exception in the
server.log which happens once in a while. We are not sure if that's the root
cause of this server getting shut down.

Has anyone seen this issue before??? Could someone please throw some light on
what could possible have happened?
Thanks for any input in advance!
