SUMMARY:

At about 2000 UTC whilst in cruise at FL410 (approximately 5hrs after departure), the Flight Deck Crew (FDC) received an ECAM message indicating a Right-Wing Fuel Pumps Low Pressure. At 2018 UTC the FDC received an ECAM message indicating Engine #2 stall. The FDC reduced thrust on Engine #2 as per ECAM actions,  and Since there was no exceedance of engine parameters, the engine was not shutdown. The FDC increased thrust on Engine #2 twice after the initial Engine #2 stall ECAM message, and on both occasions the FDC received further ECAM messages indicating Engine #2 stall.
The flight continued to Johannesburg (FAOR) with manual thrust control and landed safely without further incidence.
