[jira] [Created] (AMQ-3948) Multiple consumers retrieving same
message from ActiveMQ
Joe Roberts created AMQ-3948:
--------------------------------
Summary: Multiple consumers retrieving same message from ActiveMQ
Key: AMQ-3948
URL: https://issues.apache.org/jira/browse/AMQ-3948
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.4.3
Environment: ActiveMQ 5.4.3 running on 64-bit Windows 7 OS. 64-bit JDK.
Reporter: Joe Roberts
Fix For: NEEDS_REVIEWED
We have a java web-service (running in Jetty) that dynamically instantiates an ActiveMQ queue and send messages to the queue - the messages are integers (i.e. 1, 2, 3, etc). We have from one to many consumers that read from this queue to process these messages. Each consumer is started from a single process but each consumer is running in it's own thread or process. When we have multiple consumers running, they occasionally will pick up the same integer or message from the queue. This is not desired. If a consumer reads a message, we don't want other consumers to retrieve that same message. We're fairly new to ActiveMQ but those we're telling about this issue said it should not be happening. They think it might be that we have an ActiveMQ configuration issue. Could be we need to set a property to prevent this. Just looking for some help. I've attached our applicationContext-mcp-parallelization-activemq XML. We could have configured this incorrectly. We're using the internalAmqConnectionFactory for this queue.

-----------------------------------
You can attach any info you have, however without a unit test showing your use-case and the problem being seen it will be hard for anyone to go much further on this.

Timothy Bish commented on AMQ-3948:
-----------------------------------
Messages can be redelivered if your client fails to ACK them. Can you provide a unit test that shows your issue? Since you are on an old release its a good idea to give the latest release a try as well to see if your issue has been addressed.

Joe Roberts commented on AMQ-3948:
----------------------------------
I have tried using ActiveMQ 5.6 and the same issue is seen there. This typically happens when multiple consumers attempt to retrieve a message at the same time. Our consumers spit out logs and the logged messages occur within the same second. If the timing is outside of that, this issue is not seen and messages are retrieved normally. If our client was failing to do something, I would expect this redelivery to occur all the time. The timing on this also makes it difficult to lock down in a unit test, though we can try. Would our logs or the activemq logs be helpful here?

----------------------------------
Thanks Timothy. No need to go any further anyway. We couldn't reproduce the problem with a j-unit - activemq worked fine in that scenario. So we looked elsewhere for the issue and found it to be something internal to our application. We've fixed that - works fine now. Resolving.
