Re: CUCM 6.1 CPU UTilisation

You may try restarting the server after upgrading CUCM to 6.x version. CPU spikes on a Cisco CallManager server can be normal depending on what service/application runs at the time. But, sustained CPU spikes are not good and can cause the CallManager service to terminate or issues like delayed dialtone, and so forth.
