What version of mod_python/Apache are you using? If you use anything before
3.2.8 you may have problems, especially if using Win32 or worker MPM on a
UNIXish system.  The latest version is actually 3.2.10, so use that if you can.

Do you use sessions in your mod_python handlers or PSP pages? Do you use PSP
error pages? Do you have the PythonAutoReload option set to Off? Do you have
multiple distinct mod_python applications running under the same Apache server?
Have you isolated each application to run in a separate interpreter space using
PythonInterpreter?

Do you see any error messages in your Apache error logs?

The above information and anything else you can think of that might
be pertinent would help.
