Producer flow control not working when there is only one pair

[Dan Tran]

Hello,  I am testing the producer flow control of activemq for both 5.2 and
5.3-RC2.   In my test bed, I have a number of producer an consumer topic
working in pair.  When I have multiple pairs running at the same time where
the producers are out pacing the consumers, the flow control feature works (
otherwise, I will get OOM )

However, when I run only one pair, i will get OOM.  Does some one see what I
see?  is there a way for me to find out if producer flow control is
triggered?

here is my configuration, using only non persistent message

  <!--  lets create an embedded ActiveMQ Broker -->
  <amq:broker useJmx="true" persistent="false" advisorySupport="false">

    <!-- Destination specific policies using destination names or wildcards
-->

    <amq:destinationPolicy>
      <amq:policyMap>
        <amq:policyEntries>
          <amq:policyEntry topic=">"  producerFlowControl="true"
memoryLimit="${fdb.broker.agent.memoryLimit} mb" />
        </amq:policyEntries>
      </amq:policyMap>
    </amq:destinationPolicy>

    <amq:sslContext>
      <amq:sslContext
keyStore="file:${FORTIDB_HOME}/conf/.jmsBrokerKeyStore"
keyStorePassword="${fdb.broker.keyStorePassword}" />
    </amq:sslContext>

    <!--  The maximum about of space the broker will use before slowing down
producers -->
    <amq:systemUsage>
      <amq:systemUsage>
        <amq:memoryUsage>
          <amq:memoryUsage limit="${fdb.broker.memoryUsage} mb" />
        </amq:memoryUsage>
      </amq:systemUsage>
    </amq:systemUsage>
    
    <amq:transportConnectors>
      <amq:transportConnector
uri="${fdb.broker.protocol}://0.0.0.0:${fdb.broker.port}" />
    </amq:transportConnectors>


  </amq:broker>


Any advice is greatly appreciated
