ICMP Redirect on Resolvers

Hello everybody,
I have two DNS Server (resolver) running on FreeBSD 9.0, I always see in
console messages like this:

icmp redirect from =>

and lots of messages like this, mostly ip addresses not belong to me, and
some times these resolvers stop working.
My question is what are these messages? why they only shown in console of
these servers not others? And are they cause the problems like stopping
working for server/services?
