How do you determine "free memory"?  I ask because it's not something
you really want a lot of with a UNIX machine.  Most of your "free"
memory should "go down" after boot in exactly the manner you describe as
the buffer cache fills up.  This is good for performance.

What does "my cgi's can't run anymore" mean?  What actually happens?  Does
Apache run the processes, does it log anything to httpd_errors.log, do
they produce _any_ output?

My concern is that you have a misunderstanding of "free memory" and are
pinning on its low value, the blame for some unrelated problem.

Ciao,
Sheldon.
