In my dmag9_input.txt, I used:
Spatial sample rate = 8
Range (color) sample rate = 16
Lambda = 0.5
Hash table size = 10000
Number of PCG (Preconditioned Conjugate Gradient) iterations = 1000
Scale parameter of Geman-McClure function = 1.41
Number of IRLS (Iteratively Reweighted Least Squares) iterations = 1
In general, if DMAG9 leaves out black pixels in the depth map, you can either slightly blur the reference image (Gaussian blur is fine) or increase the spatial sample rate.
