## Discrepancy

WHILE IN CRUISE FLIGHT, CREW RECEIVED A MASTER WARNING AND RED CARGO SMOKE CAS MESSAGE. THE WARNING MESSAGES REMAINED ILLUMINATED BRIEFLY THEN EXTINGUISHED.  AS A PRECAUTION, A CREW MEMBER WENT BACK TO CHECK THE BAGGAGE AREA FOR ANY ANOMALIES.  NO SMOKE OR OTHER INDICATION OF A PROBLEM WAS NOTED.  THE FLIGHT CREW CONTINUED TO THEIR SCHEDULED DESTINATION WITH THE SAME CAS MESSAGES REAPPEARING PERIODICALLY ENROUTE, LANDING, AND TAXI.
