> Failure Detection has a possibility to a race condition with the processing of the client packets (or frames in the case of AMQP).
> This is because Netty detects the failure and removes the connection objects while the packets are still processing things. 
> I was not able to reproduce this particular issue, but I have seen a case from a memory dump where the consumer was created while the connection was already dropped, leaving the consumer isolated without any communication with clients.
> That particular case I could see a possibility because of these races.
> I am adding tests to exercise connection failure in stress and I was able to reproduce other issues.
