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

[Manish Gogna]

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

[Hythim Ali El Hadad]

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

Hi, sorry for delay on reply.

Issue was resolved after reboot.
