It may be related to:

   http://issues.apache.org/jira/browse/MODPYTHON-109

Problem is that mod_python tries to call Py_Finalize() when child  
process
being killed off, but it is being done from inside signal handler  
context which
is quite bad. Similar problem if you use req.server.register_cleanup 
() or
apache.register_cleanup(). The latter functions may have to be removed
if no equivalent can be found that is safe.
