Hello,

we are using an enterprise bean inside JBoss which connects to a local queue manager. Everything usually works fine and the code for this hasn't changed and neither has the MQ installation (5.3, FP5 on Red Hat 7.3), but recently we are seeing daily instances of JBoss crashing and generating a JVM core dump, the start of which is:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x51778B47
Function=zcpCreateMessage+0x197
Library=/opt/mqm/lib/libmqz_r.so

In addition in /var/log/messages we get for example

Could anyone give a possible theory as to why this might be happening?

Many thanks

So what has changed? Did you upgrade JBoss?
