Hi Alan, First of all thanks for helping to understand the meaning of these queues. How long the broker will keep those queues? Because if they exist until the broker restarts, it will be difficult to find a concrete queue because of amount of [email protected]_xxxxxxxx.

They are bound to the amq.failover exchange to receive updates on cluster membership, so that clients have an up-to-date picture of the brokers they can use for failover. They are very low-traffic (one message each time a broker joins or leaves the cluster) and are not stored persistently. They should not have any noticeable impact on performance of your application. --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:[email protected]
