When I submit an answer, I keep getting "Oops we are taking a breather". Why?

This is very aggravating. I go to the trouble of writing out a long answer and can't submit it. This has been happening a lot lately. What is the problem. I can answer other question ok, but if I answer that question again or try ans resubmit my answer, I still get Oops. What is the problem with yahoo answers?
