Tim,

We just ran another test with all 3 brokers, 2 producer hosts, and 4
consumer hosts ... and made sure that every broker had at least one consumer
host directly connected ... and we saw the queues on broker1 build up
immediately - event during the "ramp up" portion of the test. We're going to
try the same test again - but with conduitSubscriptions="true" and
decreasNetworkConsumerPriority="true" (both are currently false).

What should I look for in the logs to see if Flow Control is kicking in? I
don't think it is because the producers keep on keeping on ... it's the
queues on the brokers that are filling up - but nowhere near to the limit
(we allow 100gb for persistent messages). Producers send persistent messages
inside of transactions ... and consumers also use transactions. And we have
useAsyncSend=true.

System usage is configured as follows:

            <systemUsage>
                <memoryUsage>
                    <memoryUsage percentOfJvmHeap="70" />
                </memoryUsage>
                <storeUsage>
                    <storeUsage limit="100 gb"/>
                </storeUsage>
                <tempUsage>
                    <tempUsage limit="50 gb"/>
                </tempUsage>
            </systemUsage>
