Well, you've changed hardware and lots of software versions, so there are many things it could be. The only one that seems unlikely is your code, since that didn't change. I would suspect the major downgrade in Perl as the culprit. You went from 5.12 to 5.8. To test this, I suggest you install 5.12 on your new system and compile mod_perl against it. If you don't want to touch the system mod_perl and apache you can install your own in a different location. I use perlbrew to try out new Perl versions locally. - Perrin
