    This seems to be a cosmetic issue where the debug changes into an error. This happens during a reconnect when one of the cassandra nodes are just in the startup phase. This seems to happen around the the time cassandra jumps it status to normal. I was able to reproduce this by just restarting cassandra, this was tested with 4 cassandra nodes.
