Yes, that seems to be a part of the problem. I have added this to my activemq.xml: <policyEntry queue=">" producerFlowControl="false"> <dispatchPolicy> <simpleDispatchPolicy/> </dispatchPolicy> </policyEntry> It seems that it does not freeze anymore, but after a some time, delivery of messages to the processors becomes much slower and messages start to pile up in the queues. Looks like I have to do some more investigation ... Cheers, Jürgen
