Quick guesses:
1. You're running multiple apps in the same mod_perl and they're
occasionally stepping on one another. There's a mod_perl option to
give an app its own Perl interpreter; you might want to try that. I
can't remember what it is offhand (+parent maybe?).
2. The apps are using the same Mason cache and are stepping on one
another (having collisions between files with the same name as they're
compiled by Mason)
