I have noticed when I switch to a a console screen using CTRL/Alt/F1 I see a full screen of localhost login messages on both my KDE Tumbleweed and KDE Leap 15.6 system which I am puzzled by. Just wondering if these are these an issue or should I simply ignore them? See attached photo.

Yes, it is an issue. The only way to avoid it is to remove IP addresses from the displayed issue (oops, pun unintended) file.
There are multiple events which trigger redisplaying of prompt by agetty. E.g. IP address change (which for IPv6 by default happens periodically). On my system IPv6 addresses are refreshed every 10 minutes which triggers new agetty prompt.
The problem is that addresses themselves do not change, only validity timeout is updated. That still generates the corresponding “new address” events that is processed by the agetty.
It is unclear whether it is agetty or kernel problem. I’d say, announcing “new address” when there is nothing new is sort of wrong.
That is for Tumbleweed. Leap has older agetty version which behaves differently. There still may be several prompts after boot, but I do not expect constant prompt redisplay every 10 minutes. If you observe it, you need to troubleshoot why it happens.
You may consider bug report, although it is more of an upstream problem really.
I have run commands to see what is listening on port 9090 which is always referred to in the messages along with the IP of my system on the local Lan.
lsof -nP -iTCP -sTCP:LISTEN
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
systemd 1 root 80u IPv6 9285 0t0 TCP *:9090 (LISTEN)
and
nmap -n -PN -sT -sU -p- localhost
PORT STATE SERVICE
9090/tcp open zeus-admin
So I know what systemd is but what’s zeus-admin? Is it part of systemd under the covers perhaps?

PS. Just search the web and found a reference to Cockpit and it opens port 9090 apparently so could this be what this refers to? I just looked and Cockpit does indeed listen on port 9090 so that explains what is doing this. Now just need to understand why all these repeated messages! This is just for Tumbleweed, Leap has different data in the messages!
This happens due to periodical Router Advertisements which refresh validity timer (reset timer start to the current time) and kernel sends new address notification in this case.
Moreover, apparently the default template for the issue file only shows one address, and interface normally has multiple IPv6 addresses, so agetty updates prompt for every address.
Why I have two identical prompts for the same address I do not know.
Thanks I’ve added myself to the cc list.
