On a Linux system, if you're referring to localhost by another name
(e.g., "ar01"), make sure you have that hostname properly declared in
your /etc/hosts file.

What did you set in the configuration? network.host? This always gets
logged, regardless of hte setting, you should ignore it. I will push a
change so it won't be logged under warn level.
