A network connection was disconnected.

Server name: %4
Server address: %6
Connection type: %7

Guidance:
This indicates that the client's connection to the server was disconnected.

Frequent, unexpected disconnects when using an RDMA over Converged Ethernet (RoCE) adapter may indicate a network misconfiguration. RoCE requires Priority Flow Control (PFC) to be configured for every host, switch and router on the RoCE network. Failure to properly configure PFC will cause packet loss, frequent disconnects and poor performance.
