> Noticed today the activemq was hanging during startup. Investigation revealed that it
is tied to expiration of messages at startup. The only way to recover from this was to kill
-9 the VM and delete the kahadb message store.
> Further testing was done whereby message expiry time was set to longer period. AMQ started
up just fine. Another test was performed whereby:
> 1. subscribe for messages
> 2. send a few messages
> 3. disconnect consumer
> 4. send more messages (1 or 2 will do)
> 5. shutdown AMQ
> 6. wait for a time period exceeded the expiration time of the messages
> 7. start AMQ. at this time it should be hanging
> Logs and thread dumps attached.
