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

 

[root@btp01esx16:/var/log] pam_tally2 –user root

Login           Failures Latest failure     From

root              250    09/14/20 05:29:57  unknown

 

[root@btp01esx16:/var/log] pam_tally2 –user root –reset

I see following lines are continuosly recorded on /var/log/auth.log
