Unkillable processes held by init process

Hi all, do you know if there's any way to kill some hung process being held by init? See below:

I would like to kill those dsmc processes but I am not able to do it since they never die. Processes being held by a process different than 1 can be killed killing the parent processes but: What about those being held by init? Any solution to that without rebooting the server?

Appreciate your comments!

Yes, you can kill zombies by killing the zombie master.

But for init, it's whole purpose is to reap zombies so these are NOT zombies but orphans.

If kill -9 doesn't work, these are hung on I/O.

So, is it there any possibility to kill these orphans? Or the reboot would be the final solution? Thanks!

Only by getting the I/O to complete or error out.  But probably a reboot is the only way.

You might want to use tusc to see what it's waiting for.
