-------------------------------------

             Summary: master-slave failover leads to lost messages from DLQ
                 Key: AMQ-3941
                 URL: https://issues.apache.org/jira/browse/AMQ-3941
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.6.0
            Reporter: Andrew McDonnell
         Attachments: DLQSlave.java

The DLQ does not work as expected when a failover to slave occurs.

# Messages currently in the master's DLQ are not duplicated on the slave and so lost on failover.
# All messages sent to the DLQ after failover are lost, discarded as duplicates.  The slave log shows entries with text "IGNORING duplicate message".

The attached junit tests demonstrate the desired behavior on the master and the incorrect behavior on failover.
