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?
