check Apache::leak that will help you to track mod_perl memory leak.

A Linux machine running Apache/2.0.35 (Unix) mod_perl/1.99_05-dev
Perl/v5.6.1 mysql 4.0.1 uses increasing "used" memory (according
"/usr/bin/free"), eventually resuting in all memory being consumed.  Memory
usage drops somewhat after a reboot of apache and mysql, but not
completely.

If a reference does not go out of scope between sessions, that memory will
not be garbage collected.  I would like to test for these types of
difficulties.

Questions:

Are there tools to track total (all threads/processes) mod_perl, apache,
mysql memory usage?

What is the normal behavior for a module which connects (via a global) to a
database in terms of mysql processes started?
