Default Uninterruptible process

I have a process on aix 52-05 launched on jan 3 that i cannot kill.

I have tried:

kill -9
fuser -kuc
umount -f ( of the filesystem )

but nothing works ....

the process is a
find ..... -citme .... -exec rm {}
on a directory of a 45000 files *.txt

i think that the only a reboot can do this kill

Bye

Stefano

Certain drivers / system calls may be uninterruptible, usually when
waiting for disk or network I/O...

e.g.
one scenario is where your find traversed a NFS file-system which became
inaccessible.

If you do not want to reboot, it could do no harm to kill -STOP the
process and forget about it. If you're like me, the last part is the
hardest and you might still feel compelled to reboot. Or worse, in the
above scenario you may find yourself unable to unmount the NFS
file-system...

Get ftp://ftp.software.ibm.com/aix/tools/debug/pdump.sh
it will help to gather some data which about the hang.
If you can get service from IBM, then they may ask for
the pdump output and/or a system dump. With the dump
they for sure can figure out what is wrong here.
