Various suggestions received:
Kris Smith: try using runon to execute kill on a specific CPU
Robert Lang: try using kill -15
David Stacks: try killing the parent pid
Sreeni Prasad: try using kill -HUP
David DeWolfe: try attaching with dbx then using kill
Mary Hunt: try renice to lower the priority
Chris Bryant: ps aux | grep ar and see if the 'S' field is U
Dr Tom Blinn: create a crashdump for HP support to diagnose
Results are that renice 20 works, so at least the rest of the system
isn't impacted. But all the others fail to have any effect, and dbx
also seems to lock up when trying to attach the process.
I can kill dbx using the 'runon' syntax so at least the situation
is no worse. I do have a support contract so when there is a low
traffic window I'll attempt to create a crashdump and raise with HP.
Thanks all for your help.
If I do ever figure out what caused this, I'll post a followup.

Subject: Process stuck at 99% and cannot kill it
On a dual-CPU DS20E (5.1b pk4) I have a process stuck at 99% CPU.
I tried to kill it with 'kill -9', it just carries on regardless.
(It's just 'ar' packaging some object files, nothing too complex)
PID USERNAME PRI NICE SIZE RES STATE TIME CPU COMMAND
4559 ibarker 52 0 1720K 696K run 87:10 99.90% ar
Any ideas other than a reboot?
thanks.
