Are you using photons in your scene?  Recently I had issues with photons 
making white dots and I had to adjust the gather radius to deal with it. 
  According to the manual a radius/spacing ratio of 5:1 is recommended, 
so I used:

#declare Spc = 0.0025;
photons {
   spacing Spc
   radius Spc * 5
}

which worked perfectly.  Of course, the spacing value would depend on 
the scene.  Hope this is helpful.
