Anyone experience after migration from ver 7.1 to 9.1 the Vm for the call manager keep hitting 100% CPU?

We run VM on Cisco B series server virtualized.

Hello, I am having the same issue with B-Series virutalized servers.  All of my UC nodes : CUCM, CUC, CCX and ELM have had CPU spike to 100% utilization without anything being found in the logs by Cisco and VMWare.   We also have the same nodes on a UCS B_series at another data center and they are not having issues.  We upgraded CUCM/CUC from 8.6(2a) to 9.1(2); CCX from 8.5(1)SU3 to 9.0(2)SU1.  

We have rebuilt the troubled CUC node on the C210 servers and it does have this issue since. 

Troubled CUCM node is a freshly built PUB using latest OVA template. 

Anything feedback would be appreciated.
