Upgrade from 8.8.6 P1 to 8.8.7 added localhost server?

Hi,
Got an odd issue here, prior to upgrading the "server monitor" page showed only my configured server with it's hostname. But now since upgrading I seem to have a new one called localhost, added which reports all services failed?
Did anyone else get this?

This is a single server setup, so it should only be reporting one server. I don't really want to run any remove "localhost" commands.. as that, well just sounds like a bad idea
Under Configure > Servers, only one server is shown, which is correct as it only shows the actual server and does not show this "localhost" server. Aside from the status page everything else appears to be running fine
.
Just seems odd that this occurred and wondered if anyone else had this?

Yes, I've seen this before (in some older version). I think the issue was a misconfigured /etc/hosts

I've just checked the /etc/hosts and it's still the same as it always has been since the server was setup.
I don't think that's the issue with this one. I've had this server running and regularly upgraded for over a year now, it's been through 8.6/8.6/8.7 etc and this has never happened before.
Heck even the old server it replaced never did this.
This is just strange. Thankfully it doesn't effect operation of the system

How about posting the output of your hosts file for confirmation? You can always remove the second 'host entry'.

Hi,
Here you go
Code: Select all
#
# Hosts Configuration for Mail
#
# Version: 20170523
#
# IPv4 Configuration
127.0.0.1 localhost.localdomain localhost
147.135.186.70 mail.eternalgoth.co.uk mail
# IPv6 Configuration
::1 localhost.localdomain localhost
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
2001:41d0:000a:2b5b::1 mail.eternalgoth.co.uk mail
Code: Select all
[root@mail ~]$ hostname -f
mail.eternalgoth.co.uk
Okay, that's weird. Just logged into the admin control panel and.. the local host entry is gone - it's weird because I've made no changes on the system, bar doing "cat /etc/hosts" and "hostname -f" commands

My RSS reader pulled a different version of your post, it contained the following:
Code: Select all
#
# Hosts Configuration for Mail
#
# Version: 20170523
#
# IPv4 Configuration
127.0.0.1 localhost.localdomain localhost
127.0.0.1 mail.eternalgoth.co.uk localhost
147.135.186.70 mail.eternalgoth.co.uk mail
# IPv6 Configuration
::1 localhost.localdomain localhost
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
2001:41d0:000a:2b5b::1 mail.eternalgoth.co.uk mail
Did you actually have the second entry for the loopback adapter in your hosts file? If you did that's most likely what caused the problem.

Hi,
Yup, but oddly it's still there and I honestly don't think that's the issue because, if I remember rightly it was there for a reason, I just can't remember why
.
But either way, things are fixed now somehow:

It still shouldn't be there as it's not necessary, go to the wiki and search for "zmloggerhostmap" - that tells you how to get rid of it (if it happens again) and you can confirm your server is set correctly with this article:
