CUCM 9.0.1 on VMware High CPU Utilization Issue

[Vassiliy Zatsepin]

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.

        1 vCPU: Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz

        8192 Mbytes RAM

CUCM 9.0 has been deferred

There is no VM that matches those specs, and your CPU is a restricted performance CPU, you can only use one OVA option.

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
