Hello,

Process name ccm is peacking 91% of CPU utilization in one of Subscribers.
On cluster there are 1 Pub, 2 Subs, and 2 TFTP.

CCM service was already restart, and Subs reload, but problem remain.

We have checked and removed association with phones not registered, but problem remain.

Are there any specific tests, or logs prior to isolate this issue?

Hi,

A few points:

> Use one of the recommended OVA templates

> Check if the spike is random or occurs at a specific time. If it occurs at a specific time it could be coinciding with something like DRS backup, CDR load, busy hours etc.

> Minimum set of logs needed for one such high CPU spike instance are:

Detailed ccm traces from all nodes

RisDC Perfmon logs

Proglogs

Also, capture the output of the following:

utils diagnose test

utils core active list

show process load

 

HTH

Manish

 

are you able to solve this issue ?

I have cucm 10.5 that have very high cpu issue cause ofccm process

 

I checked traces for call manager and ris DC but didn't find the cause
