Hello dear colleagues.
There is an issue with high CPU utilization on my UCS-C220-M3 CUCM 9.0.1 Subscriber with ESXi 5.5.
I have a cluster with publisher and one subscriber.
A problem with jump of CPU Utilization in Cisco RTMT.
You can see a printscreen of RTMT CPU Usage ang load average from ssh of subscriber server.
What kind of problems could be the reason of this issue.
I have 1.5.4 HUU firmware pack now.
I want to try upgrade my UCS to 2.0.1a firmware
Can it help me?
Thank you for your answers.

I've install not from OVA file you are right, but it worked fine.
I know that in CUCM 9.1 and above you can use only OVA template when creating VM.
Then you're on a not supported system, and Cisco will not support your environment, with that CPU, you cannot use anything beside the 1K user OVA
