this has been happening to me on and off too. it's pretty aggravating. one way to get rid of it w/o doing a soft reset is to go into Settings/Sounds & Notifications/Notifications/Text Messaging and uncheck Vibrate and hit Ok. It'll turn the vibrate off, but if you go back in and turn it back on it'll do the nonstop vibrating when you get another text. The only way to correct it (albeit temporarily) is to do a soft reset. This seems to be intermittent too, there doesn't seem to be any particular action that causes it.
