Random Black Bar On The Image

[ausn]

Hi,guys!
I have a problem.
This is a frame of sequence rendered with Mental Ray.You could find a bar on the red brush area . I don't know where and when it comes up on the image.
I use an Omni light used AO shader following with the camera. Something wrong with my lighting setup? Or any other reason?

Thank you!!!
