Again, if you're using OcclusionMaster by Face_Off, that product applies an Ambient Occlusion node to your materials in the material room. The AO, in this case, would not be controlled by a light, instead, it's controlled by a material node. In fact, you don't need to have AO enabled on a light at all if you're using it on a material, so that could be causing problems right there.

To adjust the bias on AO node, go into the material room and select whatever material is giving you problems, and adjust the bias on that node.

You can run OcclusionMaster again, and increase the bias setting for all your AO nodes at once from the python panel. Keep in mind, there are two ways to apply ambient occlusion to objects in a scene. One if by enabling it on a light source (which applies the AO to the entire scene, and all objects in it), and the other is by using the AO material node on your objects in the material room, which is what OcclusionMaster helps you with.
