Actually Jeff, I think you were right: The SESSION_CLOSE won't suffice as a LAST message since many sessions can share the same connection, so I think you need a CLOSE message on the connection.

This is still happening....

To replicate:

ant runServer

ant runListener

Ctrl-C

ant runListener

ant runSender

The listener hangs:
[java] 07:32:42,926 INFO [org.jboss.core.example.PerfSender] received 96000 messages in 9.66s [java] 07:32:43,080 INFO [org.jboss.core.example.PerfSender] received 98000 messages in 9.81s

It doesn't receive all the messages.

I was running this on my branch created two days ago.

Unless someone fixed it past 2 days. I will validate it on trunk later today.

did you wait for the connection TTL to be hit (5 minutes)?

I tried it and the connection TTL is effectively hit but the messages sent to the 1st listener's buffer are not put back in the queue.

The code is good. It happens in the trunk because the server *pre-acks* the messages it delivers to the perfListener.

If I set pre-ack to false, the messages are all received by the 2nd consumer when the connection TTL is hit and the server clears up the 1st consumer resources.
