Thunderbolt Gigabit Adaptor
Has anyone encountered a situation where the Thunderbolt Gigabit Ethernet adaptor is flaking out and temporarily loses connectivity? The Network pane in System Preferences never reports that connection is down. What we see is that connectivity stops for a short time and then comes back.
We've seen this on iMacs where we are using the gigabit adaptor for the LAN connection and the built in for the private metadata connection.
