Description of Issue

sms-200 was streaming for several hours when it stopped cold. Roon app was showing progress bar that flashed back-and-forth rapidly.

Roon Radio was in effect, no tracks queued except the current. I signed into NUC and got this status:

Maybe this one?

Roon Appliance Core Dump?

Roon doesn’t get on nicely with NetworkManager which manages network devices and connections both on Ubuntu Desktop and Linux Mint. You have basically two options: If your Roon core runs on a headless Linux server, I would simply install Ubuntu server which doesn’t suffer from this problem. I have done so myself. The other option is to reconfigure your Linux so that it doesn’t use NetworkManager to manage network devices. Instead it can delegate to networkd which is default on Ubuntu Server. P…

This is a clear case of roonserver crash complete with a full stack trace.
Hopefully, roon folks would like to take a look and determine its cause.
This is one and only crash in 40 days or so.
I won’t be making any changes to the server machine. Blindly making changes for a hopeful fix is not the engineer’s method.
