jijun wang commented on AMQ-2985:
---------------------------------

I just tried on Nov 12th SNAPSHOT build. It now will receive the same message more than once.
For example, I have some durable message sent out every 20 minutes. A client may receive accumulated
durable message 3-7 when it first reconnects. Then the client disconnected. After more than
20 minutes, it reconnected second time and received message 8. It then disconnected again.
After another 20 more minutes, it reconnected the third time, but this time, it received message
3-9. So message 3-8 were delivered with duplicate.

I have the following configuration for AMQ broker:
<destinationPolicy>
            <policyMap>
              <policyEntries>
                <policyEntry topic=">" producerFlowControl="false" memoryLimit="1mb">
                  <pendingSubscriberPolicy>
                    <fileCursor />
                  </pendingSubscriberPolicy>
                </policyEntry>
                <policyEntry queue=">" producerFlowControl="false" memoryLimit="1mb">
                </policyEntry>
              </policyEntries>
            </policyMap>
        </destinationPolicy> 
 ...
        <systemUsage>
            <systemUsage sendFailIfNoSpaceAfterTimeout="3000">
                <memoryUsage>
                    <memoryUsage limit="20 mb"/>
                </memoryUsage>
            </systemUsage>
        </systemUsage>
