             Summary: Purging a Queue can lead to OOM error with prioritized 
messages
                 Key: AMQ-6069
                 URL: https://issues.apache.org/jira/browse/AMQ-6069
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.12.1
            Reporter: Christopher L. Shannon
            Assignee: Christopher L. Shannon


The other day I noticed that when purging a large Queue I receive an out of 
memory error in the broker.  I did some investigation and it looks like this 
only happens if using a Queue that is configured to use prioritized messages.  
After analyzing the heap dump it was discovered that after a purge, the 
dispatchPendingList in the Queue is still retaining all messages and not 
freeing them as it should.
