C Velo commented on AMQ-2887:
-----------------------------

I can also see the negative queue counts in JConsole as well.

Haven't been able to reproduce a test case with this using JMeter, however,
I have been able to reproduce this via using an in-house test script which
puts large #'s of our application-specific messages on the application queues.

+Scenario:+
            • Producers: 3
            • Brokers (network of brokers): 2
            • Consumers (application consumers): 2

Our message sizes are small - all of them under 1k.

----

To reproduce, start up multiple Producers, both of which are throwing 80,000+ 
messages
at two brokers (which are networked together) and have the two consumers 
running on 
separate servers pulling items off of the application queue.

----

+NetworkConnector snippet:+
{code}
        <networkConnector name="ActiveMQ Cluster" 
uri="static:(tcp://broker1:61616,tcp://broker2:61616,tcp://broker3:61616)" 
conduitSubscriptions="false" dynamicOnly="true" 
decreaseNetworkConsumerPriority="false" 
suppressDuplicateQueueSubscriptions="true" duplex="true" networkTTL="5"/>
        </networkConnectors>
{code}
