I am doing a simple keyframe animation with a ball and I am having a strange problem. When I batch render the animation, the ball will disappear for several frames in a row. Each time I batch render it skips the object on the exact same frames. There is nothing special about this file, just a simple ball and some plain geometry.

If I render the problem frames manually in the GUI the ball will render in the scene with no problem.

Has anyone seen anything like this before?
