You're welcome. I suggest you think about removing the recursion that Helter pointed out, too. I never noticed it when I skimmed your program the first time, because I was only looking for the cause of your zombie problem. Wouldn't it be much cleaner to structure your code like 
   while (1) {
      process_files();  # loop(), essentially
      sleep $interval;
   }
