The Landau problem on the evaporation front stability is generalized to the case of finite thickness of the evaporating liquid layer. The analysis of the influence of additional factors, the impermeability condition of solid wall and resulting pulsations of mass velocity, is carried out. Parametric calculations of the stability boundary are performed when changing the liquid film thickness and the relationship between phase densities in the framework of asymptotic Landau approach for the Reynolds number Re > 1. Approximate evaluation of the influence of liquid viscosity on the stability boundary has been done.
