Cause. ServerNet hardware cannot achieve satisfactory progress when receiving data
on the specified port and has brought the link down. The reason is usually a problem in
the local ServerNet hardware or timer settings, not congestion in the fabric.
Effect. The port is down. Data in the receiving buffer is discarded, possibly causing
timeouts at the sender's end.
Recovery. There is no user-level recovery. ServerNet hardware and software monitor
the status of the port and automatically recover the port when it is operational and can
transmit data without errors.
