> I believe I have found a bug in message order delivery in ActiveMQ. I have taken the example benchmark consumer and producer programs and made the following modifications:
> 1) Added a counter to keep track manually of the message order.
> 2) Made the transmitted number of bytes per message random between 1 and 64 bytes.
> 3) Added a random delay between 1 and 10 seconds triggered after every 100000 messages transferred on the publishing side.
> After running for a few minutes I begin to see violations in the message delivery order. In my most recent run I have counted 54 violations over the course of an hour.
