The black hole are caused by the frame buffer running out of memory, things to try

1) generate your FG/photons at half the image resolution, freeze and rerender at full res. This is a good practice regardless of black buckets or not

2) Turn off the frame buffer

3) render through backburner

4) Play with the BSP settings

5) Use mrProxies (maxdesign2009 only)

6) optimise your FG/ Photon settings to be more efficient. Often the presets can be too high, start at Draft then Low, medium and High can be killers
