Why does Riak log "unavailable channel closed" message for ERROR message

I'm not a Riak expert, but it looks like the message inavailable channel closed

should be an INFO level, not an ERROR level log message. We open some Riak connections when our server boots up to fetch user data and then they timeout (which should be fine, right?) When they exit the message box inavailable channel closed

.

Are we using Riak incorrectly? Is there a REAL bug? Or is it just an INFO level because it is part of the normal Riak lifecycle?
