It spams for a while.

The Factorio service crashed and restarted from the last save.
I've added that ip to my banlist.

Thanks for the report but I'm not seeing any crash in the log you've pasted?

The log ended at 19.896. The server then restarted a created a new "factrorio-current.log". Unfortunately the server didn't go through the usual shutdown procedure like closing the socket then saying goodbye, the log just stops.
