CPU Usage is 100%.

[shikhar_1]

Hi,

I am having issue of high CPU utilization with one of HP-UX server.

I have checked and found one process is consuming max cpu. See the below findings.

Can i kill that -sh process??

Appreciate quick response.

I think it would be safe to kill

It looks like a shell from a session that was terminated incorrectly.

Killed -sh process but still the CPU usage is showing high.

Well, yes it is.  You now have other process that are using CPU.

The 3 bpbkar process are using a combined 83% CPU.  You need to determine if those are valid processes or not and whether or not they can be killed.

>but still the CPU usage is showing high.

Not much you can do about it except get more CPUs, RAM or a faster machine?

Or schedule your bpbkar processes later?  A similar URL:

What does "swapinfo -tam" show?

[suvy12]

can u check for background processes if any running

Run

#fg

(It would help if you could go back and edit your post to make the output readable.)

>memory 9450 1399 8051 15%

So you have free memory and aren't swapping.
