Any ideas?

Two ideas actually. The first is to search for memory leaks with something like Devel::Cycle or Devel::Leak - maybe you just have a circular reference somewhere that prevents perl from destroying the objects.

The second idea is to spawn a new threadprocess for each task, and let the operating system clean up the memory for you.
