ImportError: No module named 'sysmon'

Question

This is my first release of a new Django app on my production server. Locally it works perfectly but on my production server I get the following 500 Internal Error. I can't figure out what sysmon referees too.

from my log file:

And also I've just notice that when restart the server I get the following error (RuntimeError: populate() isn't reentrant ):

Answer 1

Frozen modules are modules written in Python whose compiled byte-code object is incorporated into a custom-built Python interpreter by Python’s freeze utility. See Tools/freeze/ for now.

From https://docs.python.org/2/library/imp.html#imp.init_frozen

It looks like somewhere someone's freezing some python code and not including all the necessary bits? It's a little tricky to diagnose after that. Try looking for something called sysmon locally.
