Andrew McDonnell updated AMQ-3941:
----------------------------------
Attachment: DLQSlave.java
> 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.
