Re: Shutdown problem -- cron job related?

At certain times, seems Friday noontime, I am unable to shutdown the system.
Instead of the usual scripts to killing all processes, unmounting everything
and will now halt, goodby, I get:
process running pstree (or something like that)
At this point, the system (or at least any console or UI) is dead.
What it this?

Just see which process is running pstree.
"ps -eaf | grep pstree"
You could find the parent pid of pstree (second column).
Look at the parent of pstree, and the process started this one.
If you go back that way, finally you will reach init, but before that you could
find which system process started these processes.
