So one of the difficulties with async programming in python is catching exceptions, add in some interesting aspects of AMQP and knowing what has happened where can be difficult. If you could provide a traceback beyond the exception it would be helpful.

You may be getting a remote close from RabbitMQ. You can check your rabbitmq logs to see and you can handle it in your code.

I would suggest adding an on channel close callback (this is rough untested code):

from pika import spec

def my_callback_function(frame):
 print frame.method.reply_code
 print frame.method.reply_text

callback_manager = connection.callbacks.add(channel.channel_number, spec.Channel.Close, my_callback_function)
