Celery back-end failure?

Question

I messed something up somewhere.

I'm using celery to run a task that runs other tasks. I'm using RabbitMQ as my back-end.

When I start-up my computer, I immediately have erl.exe taking up 50% of my CPU resources and several gigs of RAM. If I let it go, the RAM usage will continue to climb pretty steadily. (the drop is when I ended the process)

If I end the process, celery beat/workers error out out with

[2014-04-17 12:35:07,869: ERROR/MainProcess] consumer: Cannot connect to amqp://guest@127.0.0.1:5672//: [Errno 10061] No connection could be made because the target machine actively refused it.

If I don't end the process, the workers and the beat just spit out the config info and then hang.

If I try to use discard_all() it also hangs while the RAM usage steadily climbs.

Is there a way I can reset erlang without going through celery? I don't care about anything in the queue, it's all dev stuff.

EDIT:

Here is the end of my rabbitmq log file.

Answer 1

I ended up:

1. Uninstalling RabbitMQ and Erlang.
2. Removed C:\Users\username\AppData\RabbitMQ
3. Restarted because at least one piece of Erlang (epmd.exe) was still running.
4. Reinstalled Erlang and RabbitMQ.

Hello, IT. Have you tried turning it off and on again?
