Yeah, I don't think this is a condition that always warrants being logged at the WARN level. The detector is supposed to see servers come up and down - it should not spit out a WARN message just because it sees a server go down. In my case, I explicitly shut down my server and was expecting my detector to see it go down. Seeing a WARN message made me think that something "bad" happened, when it really didn't.
