I think this session is associated to the network of broker topology between (multicast) my two "equivalent processes".
I think I have several problems. However Close() seems to let the process in a cleaner situation. Here it is an other problem where "multicast" network of brokers are broken when several processes in the same network of brokers try to terminate simultaneously. I will try not to stop them simultaneously and see if the problem appears when I want the second process to die gracefully. And the number of consumers which increases is perhaps the AMQ-2109 which is resolved in 5.3. -- View this message in context: http://www.nabble.com/Do-you-know-when-ActiveMQ-Session-threads-die---tp24071802p24332324.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
