The basic problem is that JBM messages appear to be getting stuck in a queue somewhere. I don't know where they're getting stuck and I don't know how to troubleshoot it.

I'm using JBM 1.4.1.Beta1 and JBoss AS 4.2.2.GA. I'm also using JBR 2.2.2.SP8.

I'm using a clustered queue on clustered JBoss application servers.

Non-clustered JBoss instances containing MDBs are configured to consume the messages from the clustered queue. I'm using a JBM bridge to take messages from the clustered queue and deliver them to a local queue on the non-clustered JBoss instances which are then consumed by the MDBs.

Anyhow messages all flow nicely for a while but then it all get jammed up and stuck and petty quickly nothing is moving. 

What do you think is going on?

How do I even begin to trouble shoot the problem?

I tried using the JMX console but it shows nothing in the queue (listAllMessages). In fact I've never seen the JMX console show anything in the queue ever and I believe it's malfunctioning. It always returns "[]".
