First I'd verify that mod_python is the problem, i.e. if you remove
LoadModule, does httpd then start OK?

Second, I'd try to compile it without the customized Python if possible. I
don't think it's the problem, but who knows.

Another thing to look at is the ipc resources with the ipcs command - I
don't remember whether Apache uses system v ipc on RH9, but if it does,
it's possible that there are no more locks/semaphores available,
especially if httpd quits abnormally. You can clean them up with ipcrm (or
by rebooting the server if you're lazy). But if Apache does NOT use sysv
ipc on RH9, ignore this paragraph. :-)
