1. As far as I know, I am not running any other apache modules using 
MySQL ( I am not sure how to check this out definitely, but I cannot 
seem to find any references anywhere to such modules....)

2. Yes, I built mysql,mod_python, python, MySQL, apache,.... from source.

Also, everything (my entire mod_python application, including all mysql 
accessing), seems to run *fine* on my home machine (redhat8-based). It 
is when I have tried running on our redhat-9-based server where these 
problems start to appear....(note that I reuilt all the sources on the 
redhat9 machine...)
