When they called they were dumping fuel with intentions of returning to ZZZ.  They dumped 82;000 lbs of fuel at X;X00 ft.  The fuel jettison system failed before they could get under max landing weight.  They continued to burn the remaining amount in a holding pattern.  Flight [advised ATC] and landed the aircraft safely.
