There are some known memory leaks.

   http://issues.apache.org/jira/browse/MODPYTHON-172
   http://issues.apache.org/jira/browse/MODPYTHON-181
   http://issues.apache.org/jira/browse/MODPYTHON-182
   http://issues.apache.org/jira/browse/MODPYTHON-184

These have been addressed in mod_python 3.3

All I can suggest at the moment is you set up a system which uses the
latest mod_python source code from Subversion source code repository
and see if the leaks go away.
