We consider an accreting central symmetric object that is near to the Eddington limit, i.e., the luminosity pressure is balancing the gravity. In special cases, a layer of accreting matter will be formed near the surface of a centrally symmetric object. We discuss the conditions of formation of the layer, its inner structure and stability. If the luminosity pressure will be reduced for some reason, then the layer will collapse immediately, releasing an enormous quantity (up to 1042 erg/sec) of energy. We discuss some possible scenarios for energy releases.
