RabbitMQ / Celery with Django hangs on delay/ready/etc - No useful log info

Question

So I just setup celery and rabbitmq, created my user, setup the vhost, mapped the user to the vhost, and ran the celery daemon succesfully (or so I assume)

(         


        

Answer 1

I just fixed a really ugly bug that would only show up for new users that would have caused this. (http://github.com/ask/celery/commit/a9c1316b15055b67ee3c38d294461fa82ed6d2b5)

Please pull from the master branch at github. If it still doesn't work you probably have to stop rabbitmq, remove the rabbitmq database directory (usually /var/lib/rabbitmq) and start rabbitmq again)

Really sorry for the inconvenience. The bug happened because we recently changed the name of the consumers routing key option to "binding key", but the amqp libraries still use routing_key and we forgot to rewrite the option.

Answer 2

For anyone stumbling upon this: it really does seem to help to remove your /var/lib/rabbitmq, even if the problem seems to go away with updating celery. I was seeing lots of unreliability and unpredictability until I did so.
