Re: CCM 4.2.(3)sr1 High CPU utilization

Try the following to resolve the high CPU utilization issue:

Click on Service parameter and Select Cisco Callmanager Service. Under the System Parameters, change the value of CDR Enabled Flag to True and restart the Callmanager Service.

Could you please comment, why CDR process in enabled mode will help to process CCM live beter?

I'll try it. Then replay aboute results.

Re: CCM 4.2.(3)sr1 High CPU utilization

Which exact version of CCM? Any SR or ES ?

Which MCS OS you are using?

Check MCSver.exe under C:/utils

How many servers in the cluster?

This server is PUB or a SUB?

Excellent picture, could you please go to Processes Tab and see which process is consuming CPU.

Check out this:

Re: CCM 4.2.(3)sr1 High CPU utilization

CCM version 4.2(3)sr1

OS version is 2000-4-4sr2

2 servers in claster.

Aboute 350 ip telephons.

all unnorman CPU utillization is the process "ccm.exe" up to 100%.

It's the same picture on both servers on PUB and on SUB! in the same time. it's depend how much time server not reload. But if servers reload at the same time the picture is equal on both servers.

Check registrations - phones on network but not built in CM. Also check any VG248 gateway which has ports enabled in VG but not created in CM. Use menu in VG to manually disable any ports not built in CM. Unbuilt ports will continually attempt to register and can peg CPU ccm.exe.

We don't use VG.

I agree - check on processes tab and see if it's CCM or something else that's chewing up the CPU cycles.
