I'm very interested in this warning as well. What I've noticed when I've got this message during meshing process I'm obtaining mesh with strange holes. This problem is raised here

Is your mesh ok when you are obtaining this error?

For that I believe you have used wrong patch name in the addLayers step. Just change the name to one mentioned in the list. it should be propably like this:

Code:
layers
    {
         hull_bodyCreatedbyGmsh   // a_surface_name
        {
            nSurfaceLayers 3;
        }
The last error shows usually when you are reading steps generated by snappyHexMesh program. Every step often contain different number of cells due to meshing process therefore it can cause problems as you have here.

Best regards.
Jakub
