It may not be related, but OP surprised me by having a FQHN for 127.0.0.1 Although many current Linux box configure themselves that way, it is considered bad practice. Try to avoid it. Hi Koos, is that because you should only have the FQDN appear once in /etc/hosts? Or is there another reason?

Hi Adam, You can have as many FQHNs in your hosts file as you wish for the same device. This is not a problem. But only for *real* devices. The lo device (127.0.0.x) should better be left alone and only have assigned 'localhost'. There's plenty of software around (Oracle, Zimbra) which will go tits-up if you assign a genuine hostname to 127.0.0.1 in certain DNS configurations. I prefer a simple '127.0.0.1 localhost'. Sometimes you find an entry '127.0.0.1 localhost localhost.localdomain'. I don't know who invented the localdomain suffix, but it seems just as silly to me.
