What do you mean by 'listener'? Do you mean you change the IP address of
the machine running the broker, or the machine running the client?

AMQP_STATUS_TIMEOUT only means the timeout that was specified to
amqp_simple_wait_frame_noblock() was reached before data was available on
the socket, or an error occurred.  Most likely the operating system hasn't
detected that the socket has been closed.
