Sounds like you have a routing loop, perhaps default routes on two neighbors pointing at each other? This is what I would suspect when I'm seeing TTL expirations. In any event, this error message is just telling you that is suspects that there is a problem, however are you actually observing poor performance or is it causing some type of outage or other issue? 241 pps really isn't that much - it's not what I would consider to be a normal flooding type of attack...
