SHORTLY AFTER XING CLARR INTXN AT 13000 FT AND 250 KTS; ATC INSTRUCTED US TO FLY THE SKEBR 2 ARR FOR RWY 25L EXCEPT MAINTAIN 13000 FT. SHORTLY AFTER PASSING SKEBR INTXN; ATC NOTIFIED US THAT WE HAD APPARENTLY MISSED A TURN ON THE ARR AND TO TURN TO A HDG OF 350 DEGS AND MAINTAIN 13000 FT. THE CTLR ALSO TOLD US THAT THERE HAD BEEN SEVERAL COMPANY ACFT MISS THE TURN TO KEPEC AFTER SKEBR. ONCE WE WERE ESTABLISHED ON THE ATC ASSIGNED HDG; A REVIEW OF THE LEGS PAGE ON THE CDU REVEALED THAT ALL WAYPOINTS ON THE SKEBR ARR HAD DROPPED OUT AND THE ACFT WAS PROCEEDING DIRECTLY FROM SKEBR TO SHAND INTXN ON THE RWY 25L ILS. UPON LNDG; THE CAPT CALLED LAS TRACON AND THE CTLR TOLD HIM THAT WE HAD NOT CAUSED A CONFLICT AND THAT APPARENTLY WE HAD SOME SORT OF PROB WITH OUR FMC DATABASE BECAUSE OF THE NUMBER OF COMPANY ACFT THAT HAD DEVIATED FROM THE ARR.
