Buchi Reddy B closed AMQ-3811.
------------------------------

    Resolution: Not A Problem

I think this was not an issue on the broker side. I fixed client side code and it started working fine.

> Hi,
> I am running ActiveMQ brokers with Shared file system Master/Slave configuration and I am seeing the following issue.
> 1. Start Master and slave brokers.
> 2. Start a durable STOMP consumer (Perl/Python) and a producer (Perl/Python) with persistence.
> 3. Kill the master broker while the producer is still sending messages.
> 4. Our STOMP library takes care of failing over to the new broker automatically and the consumer replays all its subscriptions. So, producer continues to send to the slave broker and consumer also receives all the messages from slave broker.
> 5. Stop the producer and consumer.
> 6. Restart the consumer with same client-id and subscription name.
> After this, I see that the consumer received some messages which were already delivered.
> This is easily reproducible with the above mentioned steps. I can clearly see in the broker logs that the slave broker has received acks from the consumer but for some reason it doesn't purge these messages and thinks that the consumer didn't ack them. The messages which were sent to the master broker (before it was killed) were actually getting removed and are not delivered multiple times.
> Any help here is greatly appreciated.
> Thanks a lot!!
