> Key: AMQ-3811
> URL: https://issues.apache.org/jira/browse/AMQ-3811
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, stomp
> Affects Versions: 5.5.1
> Environment: Linux operating system and Perl/Python STOMP clients.
> Reporter: Buchi Reddy B
>
> 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!!
