It works beautifully, but why does this also generate one zombie process:
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
rob 655 0.0 0.0 0 0 ?? Z Sat02PM 0:00.01 <defunct>
You get a zombie when a process has exited and the parent hasn't issued
a wait(2) (or SIG_IGN'd SIGCHLD). Have a look at what the parent process
is and that might give you an idea as to what is going wrong.
Sorry, can you tell me how to do this?
How can I find out what's the parent process of a Zombie process?
I have a user crontab, which calls a sh-shell script; so I have no
clue where to start investigating....
Thanks,
Rob.
