------------------------------------

Here is another post that may be related. It seems that the fix suggested by Pete Schwamb
fixed his issue. The fix was checked into the SVN repo r636078.

> Messages aren't always delivered in a clustered environment.
> If you have a cluster of three ActiveMQ nodes, and you send the cluster a constant stream
of messages, and randomly restart individual ActiveMQ nodes, you can enter a state whereby
an ActiveMQ node has undelivered messages sitting in the message store. These messages will
not be delivered, unless that ActiveMQ node is restarted.
> This appears to be a consequence of the fact that a Queue immediately dispatches a message
received to any available subscribers, but ignores any exceptions that result from the actual
send.
