Read the documentation for common causes:

http://code.google.com/p/modwsgi/wiki/FrequentlyAskedQuestions#Apache_Process_Crashes http://code.google.com/p/modwsgi/wiki/ApplicationIssues

Try and track it down by using a debugger:

http://code.google.com/p/modwsgi/wiki/DebuggingTechniques#Debugging_Crashes_With_GDB

Most likely your login page causes an extension module to be imported and used that doesn't work in sub interpreters. Try forcing that application to run in the main interpreter using:

WSGIApplicationGroup %{GLOBAL}

See documentation on the mod_wsgi web site for more details.
