Very much looks like you don't have a startup.pl that loads the world in the parent process.

Read the mod_perl tuning guide and settle on a strategy of MaxRequestsPerClient or a fixed Apache2::SizeLimit. Also, are you running stock apache/perl/mod_perl? Seriously consider spending time making your own build. Even recompiling the .srpms with gentoo-safe flags for that $arch could give a healthy boost. Or pay someone *cough* *cough* to do it for you :)
