      Server process (Producer) was running on Broker 1 and the client process (Consumer) was running on Broker 2.

      While an ACL update was being done , activemq.xml was touched in that process which triggered Soft restart of Broker2 . Client Process switched to Broker 3 and moved back to Broker 2 once it was recovered(since priority back up was set to true) . After that there was no communication between Server and Client . We came out of this situation by recovering the broker processes.

      Note that if priorityBackup=false the behaviour is not seen, and that with priorityBackup=true it is seen infrequently. By infrequently I mean I had to run the attached reproducer and force failovers Broker2 -> Broker3 and then back to Broker2 maybe 20 times before I saw the behaviour.
