Hi @Wilfrid_Russodivito,
Thanks for your patience over the last couple of days, we’re a small team and try to respond as quickly as possible. It’s also worth noting that replying multiple times isn’t necessary.
What the logs show
Roon Server on the Gustard isn’t hanging, it’s crashing and restarting, over and over. In the ~23 minutes of logs you sent, the server started up 16 separate times, roughly once every 85 seconds. Each time it gets partway through loading your library, runs out of memory, and gets killed before it can finish. Then it starts again from scratch.
That’s the loop you’re seeing. From the app’s point of view the server keeps vanishing and coming back, which is why you get the white loading screen and the constant disconnect/reconnect. The library never finishes loading, so Roon never becomes ready.
Why it’s running out of memory
Two things are working against each other:
- The database that was restored onto the S26 is very large, about 16 GB, containing roughly 794,000 track records. This is within the top 1% of library sizes we see, and honestly cannot garaentee normal performance on such a library. Can you confirm the machine itself can handle this large of a library?
- Your Synology music folders aren’t mounted on the S26, so Roon can’t see any of those files. It’s marking the storage as unavailable at every startup.
So on each boot Roon loads those 794,000 tracks into memory, finds zero matching files on disk, and begins a full library cleanup, essentially preparing to remove the entire library. That job needs more memory than the S26 has, so it dies before it can finish and write anything down. Nothing is ever saved, so the next startup does exactly the same thing. It will keep looping forever on its own.
The part I need your help with
794,000 tracks doesn’t match the ~1,500 albums you described. That’s a big discrepancy, and it matters, it suggests the backup we’ve been restoring isn’t the library you’re expecting, or that the database in it has become bloated or damaged. If we restore the same backup again, we’ll land right back here.
Could you tell me:
- On your Synology Roon Server, what does Settings → Library report for the number of tracks?
- Roughly how much RAM does your Gustard S26 have?
- Do you have older backup sets available, from before this started — and what dates are they?
In the meantime, one thing to try
This will break the loop so you at least have a working server again:
- Make sure the Synology Roon Server is fully stopped (only one can run on your account).
- On the S26, reset the Roon database to a fresh, empty one, do not restore a backup yet.
- Don’t add any storage folders yet. Just let it start.
It should come up cleanly and your app should connect normally within a minute or two. That confirms the diagnosis and gives us a stable starting point. Once we’ve got your answers to the questions above, I’ll tell you exactly which backup to restore and in what order to add your music folders, so we don’t trip the same problem again.
