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?
