I moved over from a Mac Mini to my Ubuntu Linux 14.04.4 server after the 1.2 release, and Roon is regularly crashing during playback to my 818v3 (ID41). The Ubuntu server is connected via CAT6 to a Cisco SG200 switch, which is connected via CAT6 to my ID41 (no wifi).
There doesn’t seem to be anything interesting in the logs when this happens it’s just playing fine and then at 08:00:36 it dies:

It was very stable on my Mac mini, but that was obviously 1.1 so I don’t know if this problem is related to Linux or 1.2.
From ps, it looks like the RoonServer process keeps running but RoonAppliance is being restarted:
