JMS exceptions in Mule 2.2.1

Hello,

I am using Mule 2.2.1 with ActiveMQ 5.2.0, and getting several JMS exceptions, such as:
Cannot publish to a deleted Destination: temp-topic://ID:magnus-63160-1245885575383-0:4:5

The exceptions appear intermittently, but often enough to easily reproduce.  The problem seems to stem from duplicate messages being received on an inbound endpoint.  These duplicate messages use the same reply-to temporary topic, and my guess is that 1 reply uses the temporary reply topic and then deletes it, leaving the duplicated message without a reply topic.

The core problem of duplicate messages may be related to http://www.mulesource.org/jira/browse/MULE-3823.

I have attached my configuration files.  A message is sent out on ZVCRouter (in transports.xml) and received by ZVCService (in zvcontroller.xml).  The result is then passed back in a request-response manner.  These processes run in separate VM's - with the exceptions seen on the ZVCService side.  Any help would be greatly appreciated.

Thanks,
Ron
