Hi Torsten, I did not find the time yet - but I will do.
Cheers ANdreas -----Ursprüngliche Nachricht----- Von: Torsten Foertsch [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 10.

I think that can be considered a bug in mp1. I remember I tried to show the behaviour with mp2 without success when the first message of the thread came in. A check on the source shows that mp2 has a ChildInit handler that resets PL_ppid if MP_MAINTAIN_PPID is defined. mp1 has obviously no such hook. Andreas, have you tried out to call Perl::AfterFork::reinit from a ChildInitHandler? It may be a cleaner solution if other modules also happen to use Perl's getppid.
