InterfaceError: connection already closed

It seems that after updating to 1.6, we are running into an InterfaceError on different views at random times. I found the some older tickets below where the issues is apparently resolved, but it's not in my case. Could this be related to the ATOMIC setting for postgres? What could I be doing in my code that is screwing with the DB connection?

The full stack trace is below. It seems to be happening while the request is starting that the DB connection has already been closed?

We are running this on:

Ubuntu 12.04

Django 1.6.5

Psycopg 2.5.3

    response = middleware_method(request)

Thanks!
