It's fairly common to see a lot of "Incomplete startup packet" in the logfiles caused by monitoring or healthcheck connections.
I wonder if it would make sense to only log that error if *at least one byte* has been received and then it becomes empty. Meaning that if the client just connects+disconnects without sending anything, we don't log anything. At least at the default log level (we could have a DEBUG level that logged "connection closed immediately").
