Avahi Daemon Log Spam


Recommended Posts

I’ve searched the forums, Reddit, Google, etc. I’m struggling what’s causing avahi daemon to spam my logs with “withdrawing/registering” over and over.

 

there are no host-name conflicts that I am aware of on my network.


nothing else is using .local TLD either.

 

there are no static IPv6 addresses assigned to any of my devices. It’s even set to automatic/dhcp in my network settings on unraid.

 

attached are the diagnostics.

@JorgeB I went ahead and disabled IPv6 and that seemed to have worked however, It's not the most ideal solution as it doesn't fix the underlying cause.

 

Here's some more log from yesterday before I shut IPv6 off. I'm thinking whatever is causing the WARNING is the cause for the log spam. The only docker I can think of that would maybe cause this is pi-hole?

 

Do you see anything else in my diags pointing to a culprit?

Maybe, I'm not familiar with it, but I don't think this is normal:

I think I found the culprit maybe?

 

nobody   19635  0.8  2.3 1609296 388820 ?      Ssl  10:06   5:39 python3 -m homeassistant -c /config

Before and After stopping HA docker and restarting unraid mDNS:

After, clearly homeassinstant is what I think is the source for the mDNS conflicting issue
