I think the Op has a "memory leak" for some reason. There are a bunch of ways that this could happen. But this post is right, Perl will re-use memory if it can. It NEVER gives memory back to the O/S and there are many ways that Perl memory gets "re-cycled" within Perl.

A "long lived" Perl program will grow to a maximum memory "footprint" and THEN that size remains constant. If you see that memory is always increasing (and not "leveling off"), then one of your objects is not releasing its memory for Perl to recycle. The main point here is that a Perl program will reach a max memory size and that's it!
