---------------------------------------------------------------

Patch attached which adds Console.WriteLines in FailoverTransport class so can see that in my test case commands are not getting removed from the requestMap object.

You'll still need to manually comment out the following lines in the OnMessage event to see the requestMap count more clearly.

public static void OnMessage(IMessage message)
{
try
{
// Console.WriteLine("LISTENER Message:");
// Console.WriteLine("LISTENER " + message);

> See http://www.nabble.com/Async-error-occurred--%3E-ActiveMQ-5.2-and-NMS-td25474605.html for a primer to this issue.
> After troubleshooting this,  it appears that if a producer sends 65535+ messages to the broker that the consumer gets into an infinite loop after consuming 65535 messages.  
> I will be attaching a test case for this.  Run a producer and a consumer, send 100,000 messages and the test case fails at 65535 messages consumed exactly.
> What appears to be happening is that the NMS provider (or ActiveMQ 5.2) is hitting the upper bound of a ushort and then starting all back over again sending message acknowledgements from message #1.  This message was already dispatched though and the broker lot shows an error that the message is not in the dispatched-list .
> The consumer shows a message acknowledgement going out.
> These errors repeat infinitely it seems.  Once the 65535th message errors out then it starts all over again at the 1st message.
> Notice the ProducerSequenceId growing beyond 65535.  I can't seem to avoid this error, even if I reinstantiate the producer sporadically.
> At the beginning of the source code I have included a loop which shows the behavior of incrementing a ushort beyond 65535.  The variable resets to the lower bound as expected.
