Would you mind answering all of the questions rather than just the first? :-)

Can you identify what changed last week? Did you change your program?
Did you upgrade Apache/mod_python? That's going to be the only way to
figure out what is wrong.

You may want to take a quick look at a couple of the WSGI
micro-frameworks around to see if they might be able to quickly
implement the dispatching you need.
