CPU Utilisation 100% due to pwgrd

[roobala]

Hi All,

We have HP 9000 L-1000 / HPUX 11.00 running as a web server in which all the Web users of the servers are having their web pages.

The authentication is by /etc/passwd , so all the users are having one entry line each in the same.

In this Server CPU Util is always 100% which had been seen from HP Perfview/Measureware agent as well as from "top", and found one process
"pwgrd" is using 97% of the CPU.

It is a Single CPU 360Mhz L-1000.
Is this is a critical where we need to go for increasing the number of CPUs
or there any way to control the util
of this particular process.

Any patches/ Kernel Tuning required?

Kindly suggest us,

Thanks in Advance,
Roobala

Add CPU 2.

roobala,

Restart the pwgrd daemon. That should do the trick. I've seen this before on an L1000 system and after the daemon was restarted this problem went away.

/sbin/init.d/pwgrd stop
/sbin/init.d/pwgrd start
(i think... I don't have an HP box near me to verify this)

Hope this helps.

I forgot to mention that the pwgrd daemon is not required to run. You can disable it if you want to (somewhere in /etc/rc.config.d/..). As far as I know, it's only used to speed up authentication. Have a look at the pwgrd man page.
