WBEM - cimprovagt is utilising more CPU (100%)

[sabinkarvijay]

Hi All,

We had a issue with one of the process which is utilising more CPU..not sure what it is for..

CPU TTY PID USERNAME PRI NI SIZE RES STATE TIME %WCPU %CPU COMMAND
7 ? 27409 root 152 20 208M 54508K run 149141:19 100.09 99.91 cimprovagt

root 27409 1876 0 Mar 6 ? 149141:28 /opt/wbem/lbin/cimprovagt 18 17 HP_NParProviderModule

I could see it's running for such a long time since 105 days..

if anyone aware, Please let me know How can i Proceed for decreasing the utilisation of CPU by that process...

Thanks in Advance,

Regards,

Vijay Sabinkari.

Hi Sabin,

I would suggest you to log a case with HP and ask for the latest patches if any.

Keep us informed.

what is your OS version ? Do you have (more than likely you do) system fault manager (SFM) installed and what is the version of that ? What type of hardware you are running on ?

There are/were a lot of performance problems related to WBEM related services. Your best bet is to contact HP under a software support agreement as this foray into troubleshooting may turn ugly real fast.

Hi Vivek/Mel,

we ran the below command on the server:

#/opt/wbem/lbin/cimserver -s

and found that the process utilisation increased more than 190 %

So went for starting the Cimserver using the below command:

#/opt/wbem/lbin/cimserver

Now there were two instances of cimserver processes running...

So went for killing the old processes which are running for such a longtime..

Now the same process is utilising very less amount of CPU...

Hope the Problem got resolved now:

If what I have read is similar to your configuration, believe me, it will come back in a few days if not few hours. So check with HP to get necessary patches for your H/W, OS and S/W versions.

Thanks for your concern Mel,

I will do that...

Shalom,

The general cause for such problems is a problem with the application.


WBEM may be patched by patches from the patch database at http://itrc.hp.com or it may need to be replaced with a new set of binaries.

The new binaries may come from http://software.hp.com or on the application DVD, which is available to users with a service contract covering software.

HP probably will recommend updating to the most current version of WBEM and all the surrounding providers.
From my experience the whole WBEM functionality is still beta software!
I have the same problems again and again, even with the newest versions. My "workaround" for this is to stop/start cimserver on a regular basis. Most of the time the cimserver is not able to stop gracefully, leaving some cimproviders running. Then those leftover processes have to be killed before restarting cimserver.

My 2 cents,
Armin

PS: Please assign points!

Hi Armin,

the process which i did for stopping and starting of Cimserver I have mentioned in this thread... is it correct?


Thanks in Advance,

"cimserver -s" should stop the cimserver and all child cimprovagt's. But this doesn't always work. After "cimserver -s" you should check that no other cim* processes are alive anymore (except cimserverd which is started from inittab).

My 2 cents,
Armin
