I recently upgraded to 6.11 from 6.8, and I have noticed that my ethernet has been cutting out sometimes.  Has anyone else seen this?

The renames are normal, have you been losing access to the server?

I was running a Pi-Hole docker container on this server, and the WebUI was hanging every 5 - 10 minutes, and that message was the only thing scrolling in the logs.  I have since removed the Pi-Hole docker container, but I am still getting the messages but a lot less frequently.  I haven't experienced loss of the WebUI recently, however, I can't say for sure that it doesn't happen.  Whenever the WebUI used to hang, and I get back in, there was always a new string like that.

If it is normal that it renames like that all the time, that is fine.  I am just wondering if it is failing when it has increased networking traffic, which would be a big problem as I am looking to add Jellyfin to the server.

Yes, I have confirmed that the web UI is basically freezing/locking up on me. Any other logs or things to list?

Enable the syslog server and post that after the problem.
