Subject [jira] Created: (AMQ-2109) Proxy Consumers are not closed when a consumer closes on a networked broker
Date Fri, 13 Feb 2009 08:02:59 GMT
Proxy Consumers are not closed when a consumer closes on a networked broker 
----------------------------------------------------------------------------

                 Key: AMQ-2109
                 URL: https://issues.apache.org/activemq/browse/AMQ-2109
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.2.0
         Environment: This is not related to a specific environment, but could be reproduced
on Linux based machines, Windows machines using  different JDK's.
            Reporter: Andreas Gies


This error occurs, when we have two brokers BrokerA and BrokerB. The simplest case is BrokerA
being networked to BrokerB with a static network connector. If a consumer is created on BrokerB
for a queue TEST, we will also note a consumer being established on BrokerA for that Queue,
which is the intended behavior. If the consumer is closed on BrokerB, the proxy consumer on
BrokerA continues to exist. Now consider the client reconnects due to failover reasons to
BrokerA this time. BrokerA would then have 2 consumers on TEST, causing a portion of the messages
being consumed by the proxy consumer. 

So, when a consumer is closed for a queue, the proxy consumers in the peer brokers should
also be closed.
