ESXi root password is getting locked frequently
I found that no machine/agent is used to authenticate ESXi server:
I rebooted ESXi several times.
Same issue.
Earlier the ESXi version was:
VMware ESXi, 6.5.0, 8294253
I even upgraded ESXi to patch but still seeing same issues:
VMware ESXi 6.5.0 build-16576891, Update 3
