I think you have logrotate (tool to rotate the logs so you dont get a huge big log file) added to your crontab jobs that is doing this. This is most common with some webhosting automation panels like cPanel etc. I cant see any important info except the alert about not being able to determine server's fully qualified domain name which isnt itself a big deal. However you mgith want to do that too. Hope this helps you
