Many thanks Gary, I tried setting the policyEntry useCache=false to no avail.
To give to some more background, I have a durable consumer subscribing to messages on an activeMQ channel and sending them to a database in an XA Transaction. A producer sends 1000's of these messages to the activeMQ channel. I've seen other circumstances where the consumer connection is restarted and the pending messages flow through (these connections were not involved in a XA transaction ), but when I flush the consumer connection pool for my durable subscriber in the above case nothing flows through, requires a broker restart. Possibly related to a slow consumer, are there any other techniques you could suggest that may help manage this situation. I would like to get away from restarting the production broker each time this happens.
