Environment

VMware vSphere ESXi 7.0.x

Cause

These events are being generated by a script called vnicen.sh located in /etc/init.d/ and is installed when using a customized image of VMware ESXi.
 

Resolution

Engage with the associated hardware vendor for a resolution.

Workaround

• Run this command in the ESXi host command line to stop the vnicen service.
  
  /etc/init.d/vnicen.sh stop 

• Ensure that the vnicen script does not start upon reboot.
  
  chkconfig vnicen.sh off

• To confirm this setting, run the below command:
  
  chkconfig --list | grep vnicen
vnicen.sh               off
