The code in your application is likely dead locking in some way. Did it auto
recover after 5 minutes, with daemon processes which were hung being
restarted automatically?
Set:
LogLevel info
in Apache configuration.
If you aren't already forcing WSGI application to run in main interpreter
then do so, by using:
WSGIApplicationGroup %{GLOBAL}
The dead lock could be caused by a Python C extension module not working
properly in a sub interpreter. That directive will force use of main
interpreter.
You will though only be able to do that if that WSGI application is only one
delegated to that daemon process group as Django doesn't allow more than one
instance to run in same interpreter.
