Running Docker Log is freezing system

[ColonelRhodes]

I've had this issue for a long time, but didn't quite understand what was going on.

 

I would get countless number of "Received packet from invalid interface." after running 'docker log plex'

 

I read that it was some issue with avahi-daemon, but now I'm thinking something else. When I check the docker logs for plex it is rendering my system almost completely useless. the docker process uses over 100% CPU utilization and the WebUI is unresponsive. As soon as I kill the docker log command it returns to functional again.

 

Is there a way to "clear" past logs from that docker log command? Or should I be looking into another fix?

Thanks for the help. That definitely resolved my issue with the Docker logs.

 

I thought it would alleviate the issue of receiving the "tower avahi-daemon[14623]: Received packet from invalid interface." repeated log I receive in my Unraid syslog, but it did not.

 

Any clue on what could be causing that?

I ran an strace on the avahi-daemon and am finding some interesting things. For some reason, three items in my house are being mentioned in the results from strace with that error message. My network printer, my philips hue bridge, and my vizio soundbar with GoogleCast. This is what the errors look like.

I know this post is outside of the "Docker" topic, so I might move it elsewhere.
