[rabbitmq-discuss] my gen_fsm's supervisor getting channel 'DOWN' messages

I have a gen_fsm that monitors a rabbitmq queue.  Everything works
fine unti lthere is an error.

When I connect and open the channel, I put a monitor on it so that I
get a 'DOWN' message when the channel dies.  Before I down the channel
myself, I always demonitor the reference.

Unfortunately, for some reason whenever I close the channel and
connection, the supervisor starts trying to shut down my process.  I'm
opening the connection with start() not start_link(), so I don't
understand why my supervisor is being notified about AMQP connection
process states.

This is actually causing us serious problems because Erlang
supervisors can't do backoff, so this usually results in the
supervisor exceeding the restart limits and terminating the whole

Any ideas?
