Hi All
Thanks for your reply, I have 3 hosts in cluster. I migrated this particular VM to another host, but its still the same issue,
I did a cumulative internet explorer update for that VM, I think 16 GB & 8 vcpu is more enough, I feel it has something to do with 0S level or may be VM. Whenever it goes high , I login to local administrator and log off then it goes normal.
the VM is part of domain.
