I'm having trouble playing music
What best describes your playback issue?
Other
The Roon remote stalls (all platforms) while browsing or playing music
Some more info:
I’m running my Core on an intel 9i5 with 8gb ram (Linux Mint) The core is dedicated only to Roon. I had the same problem when I was running with Rock on an Intel Nuc 7i5 with 8gb ram. I hoped switching to another server would help, but unfortunately not.
The plus side of running linux is that I am able to (kinda) see what is happening.
While the app ‘stalls’ (nothing is loaded from the core), the CPU is taxed 100% on one core (see screenshot).
It also seems to coincide with my library being scanned/reindexed. (see screenshot)
I do not initiatie this reindex/scanning, it is different from a manual rescanning (which is always really fast and doesn’t make the core lock up or anything). After this scanning, CPU returns to normal and everything returns to normal. See screenshot:
Lastly, I restarted the Roon service; after this memory usage drops considerably from 7GB to about 2,5GB… No idea if this is related, but Roon seems to always creep back up to about 5 to 6 GB of ram usage, which seems excessive.
This issue occurs multiple times a day (and is very annoying). It takes a couple of minutes before the app is usable again.
The last time it occurred: Saturday the 23 of march on 19:51

How many tracks are in your library?
Is this local, Tidal or Qobuz?
If local, where is this stored?
22000 tracks, stored across a nas, Qobuz and tidal.
This issue popped up only recently since a month or two I guess. I’ve been using Roon without this issue for much longer.
How many tracks are on the NAS?
Around 8600
To me, and I could be wrong, Roon seems to be reanalysing your NAS library periodically.
To eliminate this theory until @support pick this up, disable the NAS from Roon’s monitored storage for a day. See what happens.
Just odd it happened with Rock and now Roon Server on Linux Mint. Common denominator is the NAS maybe.

I just had the issue again at 12:11 and there was no reindexing going on as far as I could see, so these things might be unrelated?
I think the common denominator is the library on the core. When moving the core from ROCK to the linux Mint PC, I used the backup and continued where I left off. The might be an issue there… Im not starting clean until @support had a look at the logs (that’s why im mentioning the time the issue occurs…)
Ah, I see. Could be the cause.
I just had a look at the logs myself. There seem to be two issues: Yesterday there was a lot of re indexing going on, especially regarding Qobuz. This a small part of the log, it went on for thousands of lines:

After restarting the Roon Appliance process, the log spam is gone and memory and CPU usage are back to normal.
Hi @Mike_de_Munck,
Thanks for the report! We’ve released some related performance fixes into our early access branch, that should hit production soon. I believe these fixes should help with your issue - let me know if you still experience them after the next update. 
Interesting. I moved my core and remotes to EA and will test it and report back.

Hi Benjamin,
Things are running a lot better. Where the issue occurred multiple times a day, it has now only occurred once sine I moved to EA. The stalling of loading the items on the remote now only lasted for about 10 - 15 seconds instead of more than a minute.

Hi @Mike_de_Munck,
We’ve released the full update over to production, you’re more than welcome to migrate back if you’re wanting to.
I experienced this issue more and more the last few days.
April 3: 19:52
April 4: 18:07
April 4: 19:23
All screens on the remote with external content simply hang loading and I am unable to change to another song. The currently playing songs keeps playing though.
The issue kicks in while browsing Roon, I cannot seem to pinpoint the exact cause.
Again, you are welcome to investigate the logs.
Hi @Mike_de_Munck,
Freezing/stalling on remote devices is still being investigated by development, so I don’t have any additional information to share at this time. I hope to have more progress to share soon.
