Re: Django throws ImproperlyConfigured error when loading URLconf on startup

Hi again,

I have managed to run into the issue on a project not using Django CMS. It also runs gunicorn with gevent.

I have a Django app running on a production server. It is handled with gunicorn 0.14.2 behind nginx. When I reload the app (by reloading the gunicorn workers), I get this error:

ImproperlyConfigured: The included urlconf myapp.urls doesn't have any patterns in it

Others with this problem have commonly noted that it occurs while using reverse in a URLconf, but I am not using reverse in any URLconfs (nor are they used in any third-party apps). Also, this error only occurs in production -- never in development (using the Django dev server) or on my staging server (also using gunicorn 0.14.2 behind nginx). It also doesn't seem to cause trouble with the site at any other time then during reloads. And it only happens for the first 10-20 requests on the website (which makes me wonder if it's some sort of race condition, perhaps).

Any ideas what's causing the problem?
