-----------------------------

             Summary: Set jms.queuePrefetch=1 Causes Messages To Be Stuck in Queue
                 Key: AMQ-4827
                 URL: https://issues.apache.org/jira/browse/AMQ-4827
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.8.0, 5.7.0
            Reporter: Yung Lai


Configuration:
connectionUri=tcp://localhost:61616?jms.prefetchPolicy.queuePrefetch=1&keepAlive=true

activemq.conf is default with no changes

Scenario:
Sent 7 different messages to the same queue. With prefetch=1 about 1 or 2 messages would get stuck in the queue everytime. After a restart of activemq the messages that were stuck in queue would be processed.

With cachingConsumers=false the messages would not get stuck.

We need cachingConsumers for better performance so setting it to false is not an option for us.

Here is a thread that is very similar to the issue.

Thank you for your time and consideration.
