Resolution

• These messages are harmless
• They simply indicate queue activations/de-activations from the netqueue load balancer, in response to network traffic variations
• In more recent versions of elxnet, these messages which are moved to debug loglevel so will not be printed in normal usage
• To stop the driver logging messages to the VMkernel the below workaround can be followed
  • esxcli system module parameters set -m elxnet -p debugMask=4627"
  • Reboot the ESXi host to ensure the changes are set
