Subject Re: ActiveMQ error browsing via JMX
Date Wed, 17 Oct 2012 14:34:53 GMT
Hi

As there are many releases of ActiveMQ, its important to tell which
version of the software you are using.

Also is there anything special about the messages on that queue? That
can cause the problem?
Did it work before, does it work for other queues etc?
