Description (last modified by Jannis Leidel)

I'm running Django 1.3 on Ubuntu 10.10 (64bit) with uWSGI (0.9.8). However, occasionally I can find such logs in uwsgi.log, reporting that 'getattr', 'isinstance' is not defined. But aren't they Python's built-in functions? Why Django unable to find them? The heavier the traffic is, the more likely this will happend.

I'm sure that there is nothing wrong with my application, but I'm not sure if this is a bug in Django or uWSGI. Can anyone give me a help?

Detail log:

This needs a bit more information to ascertain the reasons for the NameError.
