-------------------------------------
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.
