Relating view factor error surfaces to part surfaces

I am running a transient heat transfer problem with body to body radiation.  I am getting a view factor error.

 

 Calculating view factors for enclosure 4.

 Error: view factors sum = 1.1435 must be >= 0 and < 1
        (tolerance used=0.11) for an open enclosure.
        This is not the case for surface number 1376!
 Your mesh is probably too coarse.

 

This enclosure has 6 defined surfaces, how do I tell which one is the problem?  I want to add mesh refinement points only in the problem area.  I do not have any surfaces on any part numbered 1376.

 

Thanks,
