> I was stress-testing an ActiveMQ-CPP consumer client by transmitting to it a large burst
of messages (100 per second). I realised that the client hangs after receiving 32767 messages
and the broker has a log message 
> INFO PrefetchSubscription - Could not correlate acknowledgment with dispatched message:
MessageAck ... 
> I changed the size of the message from 40 bytes to over 600 bytes but it still behaved
the same way. Behaviour remained the same when I reduced message frequency to one per second.
I am using ActiveMQ-CPP-2.1 and ActiveMQ broker 4.1.1. 
> I replaced the C++ consumer with the Java consumer and the problem disappeared. Then
I ran both the Java and C++ consumers concurrently both listening to the same queue, the C++
client froze after 16 messages whereas the Java client continued to receive and process messages.
> Now, I have the C++ producer client that disconnects after sending 32000 messages, reconnects
and then starts transmitting again. The problem disappears with this configuration. Both Java
and C++ clients have now received in excess of 230k messages and are still running perfectly
well.
