A post was split to a new topic: I have this exact same issue

Roon in a container/docker env. is not an officially supported situation.
Apologies if i misunderstood your screenshot.

Is your library fully analysed and identified? Size?

4

That has nothing to do with docker it’s standard Linux htop for performance monitoring. Shows what apps are doing what work the pcs resources. Roon is using all one core so it becomes sluggish in nature. Reports by many of us, no solution in sight.

5

I know how htop looks, but the ssh session is gert@docker which indicates a container solution.

Ah yes very observant I missed that. Not had my coffee yet. Still it shows the same problem lots of us are getting docker or no docker.

Havel you done a trace in to Roonserver log to see what it’s doing. When it’s happened on mine it ends up being metadatasvc updates which is doing a full library metadata trawl and update from its services.

I did use roon rock on a intel nuc for a long periode, until this starts to happen. My roon server it often not responding for 1-2 hours.
I moved my roon installation to a ubuntu server (named docker) no docker running, to se if coud find the problem.
Roon is installd with the linux script, and there is nothing else running on that server.

I can not see any special in the roonserver_log

Do you have a way to see it?

When it becomes slow I just tail the roonserver_log.txt file or open the log up and move to the last entries. Here I can see the activity causing the issue. Which always corresponds for me to be metadata updates. Not sure if mine has had extra logging enabled by support or not but I see it pop up.

All 4 cores are at 100%
I have 16G ram and they are also fully used.

As far as i rember i have around 14K tacks in my database.

Do i really need a bigger server, with more hores power and more RAM?

12

Something else wrong there if it’s maxing 4 cores. Is the music local to the server or over network to a NAS? Is this a new installation? Wonder if it’s stuck analysing your files somehow? What happens when you stop it and restart ? Do you see a red triangle in Roons UI anywhere when using the app?

13

I would remove the Qobuz url as it contain your account token and could lead to someone hacking your account.

14

Removed

Thanks

15

The files are located on a NAS server.

If i reboot the computer it runs for 24 hours or so and the the problem is back

16

If you check in roon settings-library is it showing any activity there.

17

Only file that has been changed is https_last_port

18

Local or streaming?

Hey @Gert_Kaae_Hansen

Running Roon in a VM or Docker is not an officially supported environment. It is considered Tinkering. Roon doesn’t prevent customers from experimenting with our software in unsupported environments; however, when you do so, you also take on the ongoing support and troubleshooting for that environment.

We wanted to provide a brief explanation before moving this [thread/post] to the Tinkering section. Hopefully, other customers who may also be using your environment can help you with diagnosing and resolving your issue.

If this does not work for you, then I would recommend running Roon in an officially supported environment for the stability and support you are looking for.

Moved back to support as OP stated he’s not running it in docker further up, the pc is makes docker that’s all.
