S: Releases the connection.

O: Re-establish the connection. If the same message does not appear again, the error was likely caused by a temporary receive buffer shortage, and you may continue operation.

Countermeasure: There are not enough receive buffers. Increase the number of buffers in the relevant group in the MCF configuration definition.
