can I ask what in the world you could possibly be rendering for that requires an image 13,000 px wide?
that's just crazyness...... not to mention the fact that it sounds like you are tryign to animate in which case your resolution is way beyond HD.... so what's the point of rendering so big if there's no format that could deliver it that way.
the quick answer is you are probably running out of memory from your image size. Which would normally mean use of vray proxies and vrimg to control your memory usage. But in your case, I would first give this thread a reading...
