When Heartbeat starts up I get this error message in my logs: “WARN: process_clustermsg: node [] failed authentication”. What does this mean?
In general, this message usually means that a packet has been corrupted. It’s common to get a single mangled packet on your serial interface when Heartbeat starts up. This is an indicator that happened. It’s harmless in this scenario. It will happen occasionally under other circumstances, and as long as it only happens occasionally (like less than once an hour), it’s harmless. If it happens continually, there is probably something else going on to cause packet corruption, and this cause should be investigated and corrected.
