Strange Shell consuming a lot of rescourses

[Adrian Hannelly]

Hello,

I have noticed on my system (HPUX 11i, PA-RISK, va7400 array) and strange process that will consume almost 100% of a one CPU (see attached text file). When I go chasing it's parent PID there is nothing there but a shell. Does anyone have any idea about what this process is.?

Thanks

Adrian

Log on the box:

kill 12260

kill -9 12260

only if it will not die quietly.

Its a normal shell. It could have a program loop running in it.

Your system has substantial idle time so its not eating up your cpu cycles.

You might want to just watch it and see if it goes away. It might be associated with a cron job.

Sorry I should have included in this post that it only appears when we have issues with the va7400 array (which is quite often but that is a whole other post). So I was wondering if it was linked to any armdsp processes?

For more information you can use lsof.

When it happens, get the process PID and launch this command :
UNIX95=1 ps -AH -o user,pid,args
It will show you ps output as a tree. It will help you easily determining links between processes. Figure out where your sh is using PID, and you will see related processes.

Thanks for all you help. It appears that it is a sub process of command view. I figured this out when we had a controller failure and this mystery shell was running and I was unable to launch armdsp -a.
