One initial question I have is how are you seeing RabbitMQ hang? Is it
repeatable under a certain loading, or is it more random? If the server
is just really busy it's possible the channel is simply blocked on a
call of some sort, so it's not really exiting - do you have evidence
that the channel really is dying?
