You don't pass any arguments to $pm->finish, so (on the child side) this call is equevalent to CORE::exit(0) (see the finish sub in http://cpansearch.perl.org/src/SZABGAB/Parallel-ForkManager-1.03/lib/Parallel/ForkManager.pm).

What if you replace the system call with exec which replaces the current child process instead of spawning new subchild, thus freeing the child's memory?

Sorry if my advice was wrong.
