I have been working with JBoss for awhile and we have an application that
listens to multipule queues and topics that exist on a remote jboss server. We
are not using MDM, the application is running JBoss Server Version 3.2.5. The
applications receives the messages just fine for a period of time (Random, I
have not seen a pattern).
After turning the JMS Trace on the server that has the Queues and Topics I
found the following (Lets call this server the 'Master' server) :
This is what the TRACE looks like when it is working on the Master server.

Then at one point it just stops, the threads on the Remote server are in a wait
state and nothing happens or the thread dies and this exception occurs.
If/When the thread dies this exception is thrown.

This is the Master server TRACE when the remote server consumers stop or die.
This continues until the remote server is restarted.
