You may try enlarging the area light. It /may/ aleviate your problem by 
making the shadow line fuzyer, possibly making the artifact less 
visible. Try ading a dim and tight spot light to get some extra light 
near the problem spot (you may need as many as there are artifacts).
Using radiosity, a white box behind and to a side of the camera can give 
some extra light where needed. Make that box large enough so that it can 
have a significant contribution. It may need some ambient greater than 0 
or a diffuse >1. Not aplicable if there is a mirror showing that area.
Those are tentative suggestions and may be counter indicated for your sene.
