JBossDeveloper

I ve been running tests (say a message every 20 seconds) of our product in JBoss 3.2.3, all was fine, but after 7th day, a particular MDB was not receiving messages from a queue, the MDB was active. The queue's depth was showing the exact number of messages that were not delivered to the MDB that were equal to the exact number of request that were pending in our application. Message cache total cache size was equal to the same number of undelivered messages. Can you please give me some insight as to why this is happening. System health is good, the only reason I can see is that MessageListener thread had stopped, Is that really possible ?

Why are the messages being cached ? Why the MDB which was perfectly consuming messages suddenly stopped. The queue is active, MDB is active why is that MDB is not picking up the messages. Is it due to Heap size issues ? (Heap is far above 50M)

Moment I restart the server, all the queued messages are sequentially processed by the MDB. Please do let me know.

Thanks
Ganesh.

PS: Thanks Adrian, my mistake I should ve posted here before.

Nobody should be posting here.
As I said before this is a bug in concurrent.jar.

The "workaround" is in 3.2.4+
