Are you talking about start_link/4 in rabbit_channel? If I'm not
mistaken, this is linking the writing and the channel in the direct
case, but not in the network case.
In the network driver, the writer is started in the start_writer/2
function on a per channel basis:
start_writer(Sock, Channel) ->
rabbit_writer:start(Sock, Channel, ?FRAME_MIN_SIZE).
This then starts a new process to translate Erlang messages into AMQP
But this loop process is not linked to anything as far as I can see,
which is the behaviour that Edwin is reporting.
