> 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.
