$pid = fork;
        if ($pid == 0){ # Is a child
            $iterations++;
            sleep 1;

        } 
        ...
        }

    if ($pid == 0){ # Is a child
        exit;

I think, the problem might be there: every child continues the loop after sleep 1 and creates more and more grandchildren. Placing exit after sleep fixed the issue for me: before after.

By the way, separate shell with ulimit -u 300 was very useful for testing this code.

Sorry if my advice was wrong.
