Too little information has been provided on your part:
1) Could you provide the screenshot from the web console at this time?
2) Could you collect Ignite logs during this period?
3) What tool shows that the processors are frozen? Have you checked
Looks like it was a centos 8 bug with ksmtuned. Had a few VMs going crazy
with cpu for that process. I have disabled that service and CPU on the VM
cluster is down. I am going to wait to see if that resolves it.
