[jboss-user] [Messaging, JMS & JBossMQ] - Re: maxPoolSize and 4.0.5

[PhilipWu]

I think there should be MaxPoolSize rather than a maxSession property.

When I set my MDB to have a maxSession of 1 (to get a singleton), and send multiple messages to the Queue, indeed only one MDB is actually being processed (as confirmed in my logs). However, when I go to the JMX-console and click on the queue to which my MDB is listening, I can see that the property InProcessMessageCount has a value of 2. This would suggest at least 2 MDB's are attempting to process messages rather than a singleton. Why is this? Could this be a bug?

What im trying to do is wipe out all messages from the Queue including the one's that are in process. I am able to do this by getting access to the MBean for messages that are "waiting" in the queue and invoking the "removeAllMessages" method. However, I am unable to delete the messages that are "in process", except the one that is actively running.
