Jayaram Sankaranarayanan commented on AMQ-6634:
-----------------------------------------------
I think this is same as https://issues.apache.org/jira/browse/AMQ-4148 . After
moving to 5.9, the issue is not seen.
> Restarting Consumer results in duplicate message delivery for all messages
> consumed after restart.
> --------------------------------------------------------------------------------------------------
>
> Key: AMQ-6634
> URL: https://issues.apache.org/jira/browse/AMQ-6634
> Project: ActiveMQ
> Issue Type: Bug
> Components: JMS client
> Affects Versions: 5.7.0
> Environment: Linux
> Reporter: Jayaram Sankaranarayanan
>
> This is observed during our tests where a consumer is restarted , after which
> we see that consumer receives duplicate messages for all the messages sent
> post restart.
> Here is the test environment.
> Active MQ 5.7.0
> One Topic, with two active consumers and one producer.
> There are three JVM instances.
> 1. Runs the broker,
> 2. Runs the producer and consumer#1
> 3. Runs the consumer#2
> When instance#3 is restarted, that consumer will start receiving duplicate
> messages for all the messages that producer sends (instance#2).
> Note that consumer running in instance #2 (which was not restarted) does not
> receive duplicate messages.
> The duplicate message delivery is not just for those messages that producer
> sends when consumer#2 was being restarted. It is observed for all the
> messages that producer sends after consumer#2 is back online as well.
> Can you please confirm whether this is a known issue with activeMQ 5.7 ?
> I tried to search the issues in JIRA but could not see a matching one.
