This could be a bug. You can file a report (<http://bugreport.apple.com>) or try to reproduce it and then file a report. yes i will do this. You can determine the parent process's id by something like "ps -oppid -aux", and the first column of the output will contain the process's parent's pid. PPID is 0 ;) with you command i have just see that i also have 0 root 8000 0.0 0.0 0 0 con- Z 1Jan70 0:00.00 (X11) (i have used X11 today) Odd. I have one too: ksh$ ps alx | grep Z UID PID PPID CPU PRI NI VSZ RSS WCHAN STAT TT TIME COMMAND 0 509 0 0 0 0 0 0 - Z con- 0:00.00 (scselect) Just a hunch, but I'd guess that the real PPID isn't zero. I'd say ps is reading a struct which has been nulled, and there's another copy of the real PPID elsewhere. UTSL...
