Event ID: 1123 Source: ClusSvc

The node lost communication with cluster node '<server name>' on network '<network name>'.
If you have event 1122 along with it you can just ignore the issue. The cluster service periodically checks the public LAN (if private / heartbeat is primary for cluster communication) for cluster communication.
In our case, the NIC driver (public LAN) was older than the driver on the other nodes.
See ME311081 and ME892422 for information on this event.
Self-explanatory, it indicates that the heart-beat connections between cluster nodes was lost (network problems, remote node disconnected or crashed).
