Have anyone got problem with winmgmt.exe process in Call Manager ?
Currently I'm using CCM 4.1(3)SR4D. I know that the cause of winmgmt spiking is the monitoring software Cisco Unified Operations Manager 2.0. Currently I disable the WMI service in Call Manager, but as a result my monitoring service doesn't work. Any solution so Call Manager and monitoring software can both work without disturbing each other ? This is quite a dilemma.
Great thanks all.
There is a known bug, fixed in new versions of the OS 2000.4.X. If you have the latest version and the problem still occurs open a TAC case.
I have checked my servers, and the logging level is already set at "Errors only", but the problem still occurs. I'm using OS 2000.2.7.
We have had problems with winmgmt.exe spikes caused by CUOM, and I think we are finally over them. There are at least two bugs that could be leading to your problems...
CCM OS - as referenced above you need to upgrade your OS (via the Cisco provided upgrades, and patches) to cover for the Microsoft bug. I am now on 2000.4.4aSR10
CUOM interoperability - the bug CSCsh75491 (in new Bug Tool) specifically references CUOM causing the CPU spike. I did the work-around, and have since upgraded from 2.0.0 to 2.0.1 on CUOM to get the bug fix.
Here is a link to the CUOM bug...
I hope this helps,
