I've answered this question many times, so you should be able to find
the answer...

A stale nonce is when a device tries to re-authenticate with a nonce
that is no longer valid. We are telling them that the nonce they used is
invalid, and re-issue a new challenge and a fresh nonce. It's just an
informative message, that I propably should move away to a debug level
of some kind.
