The error message:
"premature end of script: wsgi.py"
in the version of mod_wsgi you are using would generally indicate that the
daemon process had crashed in some way.
This is why I asked for the surrounding messages from the Apache error log as
there would be other messages in there confirming whether the daemon process
had in fact crashed. Using LogLevel of info would also results in extra
messages which would confirm what was happening.
One cause for a crashing process is that you are using a Python module with a C
extension which is not written so as to be safe to use in Python sub
interpreters.
http://code.google.com/p/modwsgi/wiki/ApplicationIssues#Python_Simplified_GIL_State_API
When only running the one Python web application, you should really be forcing
it to run in the main interpreter context and that will avoid the problem.
Thus add to your configuration:
WSGIApplicationGroup %{GLOBAL}
