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

             Summary: On overlapping Failover a session can consume large 
amounts of memory trying to clear consumer state.
                 Key: AMQ-5003
                 URL: https://issues.apache.org/jira/browse/AMQ-5003
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.9.0
            Reporter: Timothy Bish
             Fix For: 5.10.0


If a consumer onMessage call is blocked waiting for failover to complete and 
send an ack and the connection to the broker is dropping as attempts to 
reconnect are happening a session can queue up very large number of scheduler 
tasks to clear in progress messages for open consumers.  Since the consumer 
will be holding the lock these can't fire so they just pile on.
