"Unkillable" processes

[Oliver Boehmer]

Hi!
It sometimes happens on my SCO-Unix 3.2.0, that I can't kill a certain
process, especially, if it's something like that:
   root  14363     1  0 12:16:02  01       0:34 tar cvfbk /dev/rct 20 60000 . 
A kill -9 xxx only has the effect, that the PPID changes to init, and after
this any kill -9 is ignored.
Why? How can I get rid of these processes w/o shutting down the system?
Hope, somebody can help me, oli
