The following message will appear in Windows Event Log with VMware Tools 2.x/3.x .
Microsoft-Windows-NDIS, The network interface "vmxnet3 Ethernet Adapter" has begun resetting.
There will be a momentary disruption in network connectivity while the hardware resets.
Reason: The network driver detected that its hardware has stopped responding to commands. This network interface has reset 1 time(s) since it was last initialized."
This behavior is related to "adaptive rx ring sizing" feature in windows vmxnet3 driver.
This feature can dynamically change the rx ring 1 size based on the traffic rate.
When the ring size is changed, vmxnet3 driver will reset the device to reflect the new configuration.
It may become random interface reset but it's expected.
