Environment

VMware vSphere ESXi 7.0.0

Cause


 These events are been generated by a script called vnicen.sh located here /etc/init.d/ and gets installed when using a Customized Image of VMware ESXi
 

Resolution



Engage with the Hardware vendor for a resolution.

Workaround:
  • Run this command in ESXi host command line to stop the vnicen service
     /etc/init.d/vnicen.sh stop 
  • Ensure that the vnicen does not start upon reboot:
      chkconfig vnicen.sh off
  •       To confirm this setting:
      chkconfig --list | grep vnicen
       vnicen.sh               off
