When using Area light with ray shadow on, there are artifacts on dark side of curvy objects. See attached image and blend file.

1.) Add a sphere.
2.) Add an area lamp
3.) Area lamp > Shadow > Ray Shadow
4.) Render

That is not a bug, but the terminator problem. Subdivide your geometry further to avoid the issue.
