    Abstract:
    We analyze the possibility that several instability points may be
    formed, due to the Paczyński mechanism of violation of mechanical
    equilibrium, in the orbiting matter around a supermassive Kerr black
    hole. We consider a recently proposed model of a ringed accretion disk,
    made up by several tori (rings) that can be corotating or counter-
    rotating relative to the Kerr attractor due to the history of the
    accretion process. Each torus is governed by the general relativistic
    hydrodynamic Boyer condition of equilibrium configurations of rotating
    perfect fluids. We prove that the number of the instability points is
    generally limited and depends on the dimensionless spin of the rotating
    attractor.
