Thanks @noris. I agree, very glad to not be crashing. 
But today while running a group of zones I noticed that I’m getting (what I think are) new error messages about re-authenticating when a rediscovery event happens. I’ve received a few of these messages that say it’s re-auth’ing until the 30th but keeps but it still refreshes:
05/29 16:50:37 Trace: [broker/accounts] doing auth refresh, next=5/30/2023 12:49:32 AM
05/29 16:51:27 Trace: [broker/accounts] doing auth refresh, next=5/30/2023 12:50:39 AM
05/29 16:52:27 Trace: [broker/accounts] doing auth refresh, next=5/30/2023 12:51:27 AM
The result seems to be that my playlists are stopping every few songs; a track will change, Roon UI will show the track is starting, then it will immediately stop. I tried to grab a batch of logs that happened immediately after a new song was started them stopped and pasted a redacted version below, hopefully it’s helpful. I notice it happens when changing from a FLAC to a low quality MP3 but I can’t say for certain it’s always only during that type of file change.
