             Summary: Memory usage incorrectly increases when messages are 
forwarded over a bridge for a durable subscription
                 Key: AMQ-6465
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker, networkbridge
    Affects Versions: 5.14.1
            Reporter: Christopher L. Shannon
            Assignee: Christopher L. Shannon

There is an issue with duplicate message suppression for durable subscriptions 
over a network bridge that is causing the memory usage counter to grow and 
never shrink.  The issue is that when the message is checked against the 
network bridge filter, a reference to the message is incremented (which 
increases the memory usage counter) but then that reference is never 
decremented so the memory usage doesn't decrease as it should.  The actual 
memory is freed but the counter continues to grow until it reaches the 
configured maximum at which point the broker can't do any work because it 
thinks the memory is full.
