Hi Team,
We have a vsan cluster with 8 hosts.We saw couple more vm`s got power reset by the HA(vmlevel monitoring is enabled and HA did the power reset after the heart beat failure)
in vmlogs we are seeing the below soft reset and multiple vm`s having the same issue...There were no snapshots running in one of the vm tools is updated and remaining ones vmtools are out dated..in windows logs there is not much insight of the issue what happed and the kernal power reset event id can be seen
