Looks like your Ray Epsilon value in the Kernel settings is not in tune with the scale of your scene. (Epsilon is usually used as the variable representing the degree of precision.) Try shifting the decimal point a digit or two to the right. Since that value controls how precisely a ray intersects with a surface, in larger scenes, you don't want to push the rays too close to the surface. If the the rays are calculated with less precision than the scale of the scene can handle, it causes floating point rounding errors start show up. Essentially, the surfaces are casting shadows on themselves.
