Hi All
Thanks to you all for the replies
Casper suggested using pstack..
on reading the man page I discovered pwdx, prints the processes current working directory
# pwdx 21320
mvfs: ERROR: view=a20029_cr217973 vob=/usr/vob/omc_Osp1 - View storage directory or control files unavailable
pwdx: cannot resolve cwd for 21320: I/O error
#
This has isolated the issue, to either a corrupt Clearcase view or Vob
which can happen.
The process is not dead yet, but we have something to work with now.
Other suggestions were
The preap utility has no effect
# /bin/preap 21320
preap: process not defunct: 21320
#
Checked the /etc/inittab file , theres no instructions to respawn the process
Thanks again

Processes that cannot be killed are generally stuck in the kernel
some place.
Have you tried pstack?
Have you tried using "mdb -k" and looked at the kernel
thread list for the offending processes?
mdb -k
> $<threadlist ! more +/programname
... look at stack trace ...
