  • And, of course, even if all memory for that string is deallocated, Perl hangs on to it and never gives it back to the OS. This is a common question on mod_perl lists: "My Apache children just keep on eating memory!"


    • Yeah, but that's something else, that deallocated memory doesn't go back to the OS.

      In this case it doesn't even go back to Perl, and that's a little worrisome if you occasionally get a peak of huge indata.

      To me that doesn't matter _that_ much since I tend to avoid long running processes, restarting the program every once in awhile. Even if Perl behaves and you code your stuff the right way, there is always some module that will mess up and not break a circular reference, or some external lib will forget to release some resource.
