Hi Mark,
Ok, when the Lease times out, it notifies JBoss Messaging, which, presumably, shuts down the server end of the JMS connection. One of the things that happens is that the bisocket ping from server to client gets turned off, which is why you see those "detected failure on control connection" error messages. That makes sense.
Now, the interesting thing is that server remains alive, but the Lease has changed. My recent changes to create a server identity wouldn't handle this situation. Ok, let me think about it.
Thanks,
-Ron
