  • I have a cluster, 2 nodes. There are repeating events id 25, every few second:

    The events intensively fill the log and sometimes network connectivity for these virtual adapters (BCK, HB) is temporary lost.

    What is problem?

  • Any new info on this?  Ever since I started seeing all these Hyper-V VmSwitch 25 events all the time, server 2016 crashes at least every 12 hours
