We consider the superconducting state of d+s symmetry with finite concentration of Anderson impurities in the limit Delta_s/Delta_d << . 1. The model consists of a BCS-like term in the Hamiltonian and the Anderson impurity treated in the self-consistent large-N mean field approximation. Increasing impurity concentration or lowering the ratio Delta_s/Delta_d drives the system through a transition from a state with two sharp peaks at low energies and exponentially small density of states at the Fermi level to one with N(0) \simeq (Delta_s/Delta_d)^2. This transition is discontinuous if the energy of the impurity resonance is the smallest energy scale in the problem.
