in thread Out of Memory Error -- Possible Leak?

That isn't possible, because Perl doesn't use a separate garbage collector. It simply reference-counts all its data (scalars, arrays, hashes etc) and frees an item when its reference count drops to zero.

(This is why circular data structures cause memory leaks.)

    then how do you explain this ?

    try:

    perl -e ' use Tk; while (1) { my $top = new MainWindow; }'
    

    it will fill your RAM at a rate of about 1MB per second ...

      If you're right about that, then it's a memory leak in the Tk module, which you should report to its maintainers. That shouldn't happen, and it's not caused by anything that Perl itself is doing.

      Seriously, I do know how Perl's garbage collection works. I'm not just pretending. :-)
