Now, I can reproduce it. Firstly, publish messages to an queue, and wait until hunderd thousands messages blocked in the queue. Secondly, login the web, click "Queues" tag on the top, and view messages in the queue. Thirdly, turn back to "queues.jsp", and you will see a consumer. If you click "Active Consumers", you will find this consumer has the same connection ID with the broker.
This kind of consumer only scan messages. -- View this message in context: http://activemq.2283324.n4.nabble.com/A-consumer-has-same-clientid-with-broker-tp4716290p4716434.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
