To expand on what magdelan said, RTN often manifests itself with certain species of SPS like Acropora, where the tissue on the coral basically just dies quickly. It's not uncommon for a whole coral to go from healthy to completely dead in a matter of hours. Often the only remedy is to try to frag some of the healthy coral and restart the colony.
I personally think it's heat related. I'm sure there are many schools of thought on the subject.

Pretty much. you can then attach the frag to a piece of reef rubble with some epoxy. This may sound *** backwards, but attach it with the cut end pointing up, not with the cut end attached to the rock. The water flow will help the cut heal. you can even attach it in the middle of the frag so both original ends are free.

I agree hyperfocal, probably many different causes.
as for fragging acro's, I've always glued my branchy sps down in the middle, so both ends are unglued. Being layed over like this seems to help them start branching off quicker than just sticking one little branch straight up.
