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
