-------------------------------------------
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.
