Description of Issue
Hello, recently Roon Core sometimes stuck if 100% CPU (on a single core) doing something, what it looks to me like internal cache maintenance.
I never experienced this before.
Roon starts playback, but it takes sometimes few minutes, sometimes it fast.
I’ve sent you the logs (see ‘Eldar Shamuely - Logs’)
Could you please look at the logs?
Have you added albums recently and it is Roon analysing them?
If so you could check your settings under settings:library and set to throtttled or even off for now and see if this helps
Yes, that’s the point, that Roon suddenly decides to scan the library, I did not add anything for weeks. I use mainly Qobuz and Tidal
Can you please check the logs?
I went ahead and enabled diagnostics. I see some errors but I don’t know how relevant they are to the issue.
The errors I see involve what is listed as your iPhone and iPad (though they show the iPhone hadn’t been used since about a month ago). Can you confirm that you were at one point listening to Allison Kraus when this happened?

In addition to connection timeouts on these devices, I am also seeing storage errors that seem to be 3d model files.:

There are also more traditional audio formats with the same error:
If you would, please duplicate the issue and provide a date/time stamp here. I will look at logging again and see if we can narrow things down. Also, can you provide a screenshot of your core webui?
