Question

I’m having trouble running tasks. I run ./manage celeryd -B -l info, it correctly loads all tasks to registry.

The error happens when any of the tasks run – the task starts, does its thing, and then I get:

[ERROR/MainProcess] Thread 'ResultHandler' crashed: ValueError('Octet out of range 0..2**64-1',)
Traceback (most recent call last):

ValueError: Octet out of range 0..2**64-1

I also must note that this worked on my previous Lion install, and even if I create a blank virtualenv with some test code, when a task runs it gives this error.

This happens with Python 2.7.2 and 2.6.4.

Django==1.3.1
amqplib==1.0.2
celery==2.4.6
django-celery==2.4.2

It appears there is some bug with homebrew install python. I’ve now switched to the native Lion one (2.7.1) and it works.
