It is most likely that there are some issues with the geometry. I suggest that you switch to wireframe mode, right click on the error message and go to the offending body to identify the problem. The faulty edges should show up in red so it should be easier to isolate the problem. Then switch back to shaded view and inspect that area carefully. You may need different repair tools depending on the type of artifact in the geometry.
