Consumer Hanging
Hi,
I am using ActiveMQ4.1, and I seem to have consumers that stop consuming at
random times. I am trying to do a large test, where one JMS message is
posted, it then gets processed, acknowledged, and then due to processing,
multiple messages may be posted onto the queue.
I am using CLIENT_ACKNOWLEDGE for the receive queue, along with
receive(5000) (note I have tried it with message listeners, and auto
acknowledge), and the post queue is AUTO_ACKNOWLEDGE.
I cant seem to work out why the consumers are hanging, any pointers would be
beneficial,
Thanks in advance,
Osian

I want to see all the stats on all the relevant subscription MBeans
when you experience a hang to deduce where the problem is. Otherwise
we've not got a whole lot to work on.

We are now running a fresh test to see if we can rule out ActiveMQ as the
problem, or even to try and pickup where and when the consumers are hanging.
Out of interest, what are you expecting as the Consumer Stats so that I can
get them if and when the problem occurs.

What do the statistics look like in JMX?
