We study the nonlinear decay of the fast magnetosonic into the Alfv\'en wavesin relativistic force-free magnetohydrodynamics. The work has been motivated bymodels of pulsar radio emission and fast radio bursts (FRBs), in which theemission is generated in neutron star magnetospheres at conditions when notonly the Larmor but also the plasma frequencies significantly exceed theradiation frequency. The decay process places limits on the source luminosityin these models. We estimated the decay rate and showed that the phase volumeof Alfv\'en waves available for the decay of an fms wave is infinite. Thereforethe energy of fms waves could be completely transferred to the small-scaleAlfv\'en waves not via a cascade, as in the Kolmogorov turbulence, butdirectly. Our results explain the anomalously low radio efficiency of the Crabpulsar and show that FRBs could not be produced well within magnetarmagnetospheres.
