Hi Elian,

Thank you for your clear answer, is my solution then still the preferred way to clean up zombie processes or is there a better one which does NOT use signals (and therefore my parent process never stops)?

Regards,
Marcello

    Try this: 
      $SIG{CHLD} = 'IGNORE';

    Depending on your platform that should prevent zombie processes.

    It's about the best you can manage. If you don't declare lexicals in the signal handler you may find yourself more (though not completely) stable. Whatever you do, don't use those variables anywhere outside the signal handler!

    If you've got Inline, you could always try writing the signal handler in C, since what you're doing doesn't really require any perl interaction.
