[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Re: Messages are lost on Queue?

[clebert.suconic@jboss.com]

There's definitely something going on.

ServerSessionImpl:cancel is called at the end of perfListener to place messages delivered but not consumed back on the queues. That's a regular operation... but cancel is canceling deliveries on messages that were not sent yet.

I had a few problems with reference counting when I ran perfSender/perfListener this way:


and perfSender -Dmessage.count=400000 -Dmessage.wamup.count=20000

and then:

run two perfListener as:

ant perfListener -Ddrain.queue=false
ant perfListener -Ddrain.queue=false


The last one won't receive 20K messages, and I believe the serverSessionImpl.cancel has a play on this bug.

This is the next thing I'm going to do as soon as I'm done with paging. I just want to make sure there isn't anything bigger than expected going on here.
