I'm running jBoss pre2 on linux with sun jdk1.3 and get the follwoing core
dump when I try and stop the server. I seem to lose all my database
information as well which is a bit of a mess. It this a fault with jBoss or
as I suspect a bug in the Sun's JDK?
Here is the dump that I get when I shut down.

Subject: RE: [jBoss-User] Core dump: ouch!
the only situation where we have seen the core dump is on shutdown where the
JVM barfs on a "unexpected thread" bla bla... then the dump goes to file and
can be quite high.
I have personnaly never seen a CD under any other circumstances (but I stand
to be corrected ;-), not even on the heavy heavy loads we are running right
now (again 200thread, 150,000 beans all in parallel and stable :)))))

|Just a warning:
|
|Just discovered that, under some circumstances, jBoss running under
|Sun's 1.3 release JDK for linux can core dump in a large way (it got
|to 116Mb before I killed it). When it's running from an NFS mount
|this drags my box to it's knees with network congestion.
