  When you stopped rendering, did you check if an extra file had
appeared in the same directory where the scene was? (Or it might appear
in the same directory as the final image is written; I don't really know
which.) It's the radiosity cache file (it is removed after the rendering
ends).

  But certainly if you render half of the image and then the other half
as a separate render (with start/end row options) you will most probably
get a visible line.
