6655 RSG received invalid message class
The class field of a message header is not of the expected type SYSMSGREPCLASS. Message was placed on either the RSG_CONTROL_MBOX or on one of the RSG sender task mailboxes. Error is recognized in RsgPSProcessMsg, or RsgCTRLProcessMsg and occurs because msgrxseg() in the main processing loop of the control task or one of the sender tasks returned an unknown message class in the message header.
