We don't always have immediate answers nor the time to look at things straight away. For me personally, I am actually on holidays in a foreign country and haven't had Internet access for about 5 days. I only have it now because I found an unsecured wireless connection. Thus, be patient. I have another 100+ messages to catch up on. Your problem isn't simple so I will be flagging it for later. Things you should at least do are try the latest mod_python 3.2 beta available from: http://www.modpython.org/dist/ You should also do a good search back through the mailing list archives as I do vaguely recollect a similar problem mentioned before. You can search the mailing list archive from the mod_python home page search box.
