I waited far too long for those words to be written 
But thank you for your service

Possibly as it doesnāt show in logs. All you see is the metadata task running if you examine those and the issue only occurs when that runs.
Iāve never had the current queue issue with it adding old history to it either or albums being split due to the various artists issue, but that doesnāt mean the problem doesnāt exist because it doesnāt affect me. Also the current Sonos bug exhibits similar behaviour also.

Strangely I didnāt have the history bug until I read about it widely on this forums. Then it happened that day (and the next), and I understood them why people were complaining about it as it completely ruined the current music listening session (for us album only listeners) and it was really frustrating. Thankfully Roon fixed it within a few days.
I have also never had the various album splitting bug, at least that I have noticed.
This bug/issue only affects me sparodically, but it impacts other users more incan imagine how annoying it is to them.
Itās fair to say that many of us add a lot of music to our library so this could happen more often.

Hmm, Iām starting to think that this is what I initially suspected. A bug in the latest software update. I never had any issues for months and months, then suddenly it just started happening frequently. Maybe it is time for all of us to start opening tickets to try and figure out what is going onā¦
@CrystalGipsy already has one open ticket relating to issues with performance after adding music that many of us have added information too (around the Metadata update process exhausting one or two full CPU threads impacting performance)
My own issues are sparodic when adding music and itās rare that music actually stops playing (though it happened twice recently).
Create a ticket and I am sure otherās will add information and anecdotes to try and help get this investigated as it needs to be

Just wanted to support you and say this is a common issue for me. I have a daily playlist that syncs with tidal, and when playing it, Iām often adding many of the songs to my library. If I start adding more than a few to my library in succession, Roon usually stops playing, audio sources show not found for a minute, eventually it all comes back to normal but can take between a minute and maybe 4-5 minutes and I typically have to hit the play button again to get the music restarted. Itās really annoying but I know itās one of those mystery problems that doesnāt seem easy to troubleshoot. I live with it and try to remember not to add multiple songs in quick succession.
I suggest that these Issues are linked or related. Music stopping. Endpoints losing contact. High CPU usage. Other threads on instability.
There are a lot of these threads. I suspect Roon knows there is a central issue but the remedy may be overwhelmed by technical debt.
My gut feeling is there is a fundamental inefficiency somewhere in the database. I can see this when I run focus queries involving many objects with Roon tags. Results take several minutes unless instead Roon has to be restarted. This may be why Roon doesnāt support and/or logic for tagsā¦maybe theyāve used it and the database bottlenecks.
So then when the database is doing anything significant, itās vulnerable to any other activity and is easily destabilized. For some this slows Roon down. For others it knocks out network connections and that also stops the music. I can see when Roon is burning a single CPU core at over 100% and that is exactly when Roon is slow or unstable.
There may also be library content that exacerbates the issue. Unidentified albums or lots or Roon tags. Or maybe even some long standing unidentified data corruption. Those without such factors may still have the same issues but not detect them due to having a different library.
So when someone says āI donāt have that problemā it may really mean āthat problem doesnāt affect my library to the point of instability.ā
It would just be nice to know Roon is on this.

Does Roon have an archive of previous versions of the software?
Iād love to go back about two months to when I never had any issues. I donāt have prior installers because Iām on ROCK and it handles the downloads and installation. Sadly, it doesnāt look like there is any rollback features in ROCK or Roon eitherā¦
No, there is no rollback possibility. Think Iāve read on this forum that some or at least one has several Roon setups. One gets the updates and the others stays on the version they are happy with.
Well they gave me inconclusive answer the usual we canāt repeat it even with a copy of my database. I know itās not a hardware limitation as I have put it in sort test for hours burning network, disk and cpu and itās doesnāt drop a beat or throttle itself. I think itās a bottleneck of its own single core activities, something they think they have optimised but hasnāt at all itās just moved inefficiencies
I use tags but i donāt have a huge amount of them, I have 9 unidentified albums. I guess these are tried to be identified each time anything changes in the db this can be metadata updated, addding new files, losing streaming connections or itās restarted as has been said by support. This is something they can address if they chose to.
The fact this is now also happening to a set of Sonos users as well after playing to them for a period of time shows something is off. This isnāt triggering any updates just core proceed gets stuck.
Also LMS which I use also will max out a core when doing library updates but this doesnāt stop the program from doing its basic task of browsing playing music etc or losing connection. This phenomenon is purely Roon. Using it at full pelt is fine as it should be done quicker but at the cost of the ability to do anything else is not good.
You might be onto something with the āunidentified tracksāā¦ Iām a Psytrance DJ and have a lot of music that is not common and isnāt listed in big music labelās catalogs. Iāve noticed that whenever the music cuts out, that the progress indicator is going and when I click on it, it says āIdentifying X of Y tracks. Z identified.ā Itās usually very large numbers like, āIdentifying 23 of 89 tracks, 1 identified.ā
Have a similar situation with my old collection of approx 1K of badly tagged MP3 files. I suspect Roon to continiously trying to find and update these , which will not happen and i will most likely not take the time to add more data to them either ā¦
I have now moved these MP3 files to a separate wathc-folder. A solution (mitigation) could be that Roon provided an option to turns off the metadata search for a specific (watch) folder.
All my recorded DJ sets (an those of others) are in their own folder, so that would likely work for me too.
BTW, I just tried to tell Roon to prefer my own Metadata in files and now my entire library is being rescanned/imported. Iāve got a bit over 1/4 million tracks and after 3 hours it is only 10% doneā¦ Trying to play anything now doesnāt really work. Hoping this isnāt going to take two days to finishing updating the databaseā¦ Just an FYI and warning to others.
Sounds like a good idea - why not post it in Feature Suggestions ?
Yeah, I saw that but figured āsome timeā meant possibly 3 - 6 hoursā¦ not 2 - 4 days.
This has been suggested before. It must be in a feature suggestion by now surely? However, it is a workaround for an issue that needs fixing. The extent to which unidentified music is part of the issue is unknown.
āSome timeāā¦ Itās now TEN DAYS LATER and still goingā¦ I think I would have been better off reinstalling Roon and importing all my music again from scratch. It should not take more than a day to process a quarter million tracks. MediaMonkey does it in 7 hours on similar hardware and that is going across a SMB network share while my RoonCore is on a NUC with local PCIe x4 SSD.
Roon is completely unusable while this process is happeningā¦ It will play one track, then several MINUTES pass before starting the next track. Same thing when you click play on the interface, several minute wait. Last night I tried to play some music on Roon, music didnāt start, so I started playing music with another app and fell asleep to the music. I was woken up by Roon suddenly starting the playlist I clicked play on HOURS earlier. This is with all the library settings set to āthrottledā by the way.
If RoonCore cannot process imports and be functional at the same time, maybe there could be a āpreprocessorā that people can use for large libraries to process music off the RoonCore and then that preprocessed information could be imported quickly to the system?
Throttled only affects tracks analysis for dynamic range and waveform creation. The metadata side isnāt configurable and uses one core only ans does all of Roons processes so it will kill it if your machines single core speed isnāt all that. The more unidentified tracks you have which I believe you said you have DJ mixes are likely to slow it down as it attempts. Your library if I remember is v large for Roon. Something itās really not good at is music not in its databases. Even when it does finish you will get in constant slow state when adding new stuff as it attempts again and again to get metatdata for stuff that doesnāt exist. Itās a really poor design for anyone with non standard metadata. I donāt think Roon is the correct choice for your collection. I would look at something else that doesnāt care about matching it.
What Iām hearing you say isā¦ āRoon isnāt good for music that isnāt popular.ā The mere fact that the the library is managed with the same (single) core that is used for playback is a DESIGN FLAW, and should be fixed. Iām so tired of being told, āIf doesnāt work, donāt use itā, rather than Harmon fixing the problem or at a minimum acknowledging it.
Remember, this entire thread and problem started after the December update and no one has been able to provide a way to rollback to the August 2024 release that did NOT have these issues. My support ticket for this issue has not been updated in weeks.
As an attempt to solve the problem, Iāve already moved all the recorded DJ sets and live performances to another directory and excluded them from Roonās library. That actually is what triggered the massive reloading of all the library and started the āapplying library settingsā process. So far this has NOT solved the issue and wouldnāt explain why so many other people are having issues as well. Iād think that the classical music and bootleg collectors would be getting hit with this problem if it is triggered by the inability to identify tracks.
If Roon cannot handle EDM music with their current lookup provider then they should get a partnership with MusicBrainz, Beatport, or SoundCloud, all of which have metadata for EDM tracks and albums. However, that really feels like a separate issue, or at least it should beā¦ Crippling the playback for all music because metadata canāt be found is a serious BUG and not an excuse.
We also know that Harmon is collecting all the metadata from our libraries as it states this in their privacy policy. If they arenāt using this metadata to help identify otherās tracks, that is pretty silly. If they are going to invade our privacy, they might as well use that data to help identify tracks/albums for other users of their service when not available in their primary metadata provider.
