Hi Peter
There definitely seems to be the rare material/light setups where it doesn't matter how long you leave the render. In these cases I've cheated and rendered with a high caustic_blur value which seems to help in the majority of cases - but there is some blur too. If the hot_pixels are due to light transmitted through glass, dropping the "indirect_light_importance" seems to help too. A few pure white materials put together magnify the light if there is too much light. I guess it's easy to put color 255/255/255 into a material, but hard to actually get something that white in the real world.
I feel like the student giving advice to the teacher....so I will stop now.
