how kill a process with PPID1

[Wood_2]

Hello

I've process dscmc (for IBM Tsm) with a ppid 1.
I can't kill the process with kill -9.

How can i proceed, to destroy this entry without reboot.
I've HPUX 11.0

Thank you for your help

Nicolas,

Sorry, if kill -9 won't do it, there's no way. Either the process is waiting on I/O to complete or it's a true zombie. If it is waiting on I/O, there's a small chance you could kill it if you could figure out how to satisfy the I/O request, but that's not very likely. A reboot is the only thing that will get rid of these.

Nicolas,
kill -9 should kill the job.
Once the process description goes to
< defunct> they normally only disappear after a reboot.

the process is not defunct.
How be sure that the process is waiting an IO.

The process backup work trough the san.

Hi,
tusc may help you identify what is going on.

It might also be the process is waiting for its children. You might check out if there are any by doing 'ps -ef | grep ' and look if those can be killed...

Hi

I've seen processes hang around after kill -9 and it is because something is keeping them alive (like child proces IO ...). along these lines check that things like Stale NFS is not part of the problem.

It seems to be io problem.

We try to reboot the server this night to free the process.

Thank you for your help.
