requests: [Errno 2] _ssl.c:504: The operation did not complete (read)

I’m using rauth in my Django application and encoutering this error. rauth is based on requests, and looking at the traceback you can see that the error indeed comes from requests:

File "/www/srv/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response
  115.                         response = callback(request, *callback_args, **callback_kwargs)

Exception Type: SSLError at /accounts/end-pipeline/
Exception Value: [Errno 2] _ssl.c:504: The operation did not complete (read)

This seems to be caused by payloads larger than usual. The strange thing is that in the development environment it works perfectly, but not in production. And this is blocking the deployment. Please help me to solve this as soon as possible if you can.

I found only another issue with the same problem here: pika/pika#59. That was solved. There is an issue in Python tracker here: http://bugs.python.org/issue12343
