My program is most likely leaking memory ;-)

I am relatively new to Perl and don't really understand how the automatic garbage collection works. If my machine has 512Meg of RAM, and I let the program run overnight, when does it decide to free the variable's memory?

Are there good techniques to use in tracking this down? or managing memory for long-running programs?

(The main part of my program uses Tk and some graphics. The graphics are being repeatedly generated and *hopefully* destroyed) (I do generate some photo's which are big, and after I am done I undef them. But this is the only case I explicitly release memeroy)

thanks!

I always seem to leave out important things out of my questions, let me know if more info is needed ;-)
