There is a Buddhist story when some monks (or followers of the Buddha) misinterpret what the Buddha is saying and commit suicide. Does anyone know anymore details about the story and where it comes from? I think it is in the Pali Canon.

Then the monks — [thinking,] "The Blessed One, with many lines of reasoning, has given a talk on the unattractiveness [of the body], has spoken in praise of [the perception of] unattractiveness, has spoken in praise of the development of [the perception of] unattractiveness" — remained committed to the development of [the perception of] unattractiveness in many modes & manners. They — ashamed, repelled, & disgusted with this body — sought for an assassin. In one day, ten monks took the knife. In one day, twenty monks took the knife. In one day, thirty monks took the knife.
Edit: I don't think the monks didn't misinterpret the teaching. Perhaps since they're still under training, their mind is not developed and overcome by disgust.
