Either you are not loading all your modules into the parent httpd
process at startup time (startup.pl, process growth is code), or your
processes are setting globals that hold data from request handling
(process growth is data related.

If you can test on Solaris or OS X, I recommend running iosnoop (a
dtrace script) which will identify what files your application
touches. If you see your application accessing modules after the app
has started, put those modules in startup.pl

Although, 38 megabytes is small. I work with applications that have
512+ megabyte process footprints.
