Subject Unclosed connection/session with large messages can bring down AMQ
Date Sat, 22 Jul 2006 04:28:03 GMT


I tried the AMQ default consumer/producer example with large message size
i.e 100000 bytes for 10000 times. During the execution, the consumer was
terminated by pressing CTRL-C, then ran the consumer again. Repeat the
termination and resumption for serveral times. The consumer and the producer
froze eventually. Even they were restarted with a new queue name and new
client IDs, still no help. Only restarting the broker can fix the problem.

On the JMX console, can see the orphaned subscription(s) by terminated

Interestingly, the original setting of the example do not reveal the problem
easily. The scenario can be reproduced easily.

I would like to confirm if this is a bug. Any workarounds?

Thanks in advance.
