If the keys have not been messed with I'd look at the permissions of the keys and/or .ssh parent directory. Has there been any IP changes to client/servers? As stated earlier, you'd see some spoofing msgs regarding your authorized_keys file and would have to make changes there if you did.
Regenerating new keys all around isn't that hard. Of course, having a strange thing like this happen makes me "nervously curious" and I would want to know why this is behaving this way first.
