Nucleus One Constantly Rebuffering / Waiting on Server

Goto Nucleus storage via its SMB share via anpc as you would adding music to it they are in the /data/Roonserver

Found them - 21 files all from today. Lots of info in them and don’t really know what I’m looking at so…

Interestingly, I turned off background audio analysis speed and no server crash for over 20 minutes. Actually got through more than one song. Seems it was stuck on 0/2047 songs every time I checked. I moved it from 1 core to throttled perviously and not just have it Off. Don’t know if that might have been the problem.

thanks,
Keith

Yep that might cause it to likely get in a loop and maybe consume all resources. Check in Roon library settings for any files it says are corrupt as this might be the issue.

Keith_Winand · November 17, 2024, 5:30pm

I turned it back on with it set to throttled and it is now processing the files and hasn’t crashed while browsing around in the app and playing music.

there are about a hundred skipped files that Roon says ‘File is corrupt’ but they play fine in other players like VLC so don’t know what the issue is there. Another mystery for a different day.

just happy that is appears Roon is working again.

Thanks to those that replied. Much appreciated.

They may well still be corrupted (not conforming to the audio format’s file specification).

I’ve had this and was able to reconstitute by using the batch convert process in dBpowerAmp.

In my case I “transcoded” from FLAC to FLAC afterwards Roon was happy.

Keith_Winand · November 17, 2024, 5:47pm

these are all .mp3 files. Can I still do the same thing with dBpowerAmp with mp3 files?

thanks

anon77144803 · November 17, 2024, 5:48pm

Yes you should be able to convert them using its conversion tool. Odd how this wasn’t an issue on your Mac though.

Keith_Winand · November 17, 2024, 5:49pm

I think it was but I just ignored them until now.

anon77144803 · November 17, 2024, 5:53pm

Fair enough it still should not be causing Roon to crash though. Maybe best to isolate them out of your library for now in case it happens again on a restart. Add them back after fixing them.

Keith_Winand · November 17, 2024, 6:07pm

I’m going to just convert them to flac and delete the mp3 files that Roon is flagging.

Don’t think this is what was causing the crash but was the background audio analysis process. Once I stopped that and restarted the os and server have been fine and playing music for the last hour or so with not problem. I have restarted the background analysis and it is processing the files with no issues. Think my issue has been fixed.

thanks

Let’s hope so.

Is the library still analysing ?

One trick is to split your library into say 4 folders then import each one singly. Once all 4 are analysed then import them all

Shouldn’t need this but it may help, it’s only the analysis phase that is processor consuming , once it’s done that’s it until you add new content

Your album count to track count seems strange , is it a lot of classical 4 track albums or something ?

Keith_Winand · November 18, 2024, 4:59pm

It finished analyzing last night but today I tackled cleaning up skipped tracks that Roon said were corrupt. I converted them to flac with dBpoweramp and now there are no more skipped files.

But… now it is analyzing the new tracked and is doing the same think - resetting the server every 3-5 minutes. ugh.

Please provide why you think my album to track count is off. I do have many classical albums but not a huge amount. I have jazz recordings with 3-6 tracks and a few anthologies with lots of tracks. Doing the math it averages 9.5 tracks per album. Here are my updated stats:

Thanks

anon77144803 · November 18, 2024, 5:08pm

They may have some duff metadata that’s copied across. Maybe a clean up of this using a tagger software like mp3tag or similar is called for. Bad tags may be the cause of it.

Keith_Winand · November 18, 2024, 5:10pm

I do have mp3tag and have used it on a large portion of my library but not all. It’s on the list of things to do…

Hey @Keith_Winand,

Thanks so much for taking the time to write in and share your report! Thanks for your patience as well - I can see you’ve been helped by some of the best from our community.

Based on a fresh diagnostic report on your Nucleus, we’re seeing potential crashing errors in relation to the available space on the Nucleus, which is odd based on your library size of 85k tracks - which fits the scope of the Nucleus One.

While our team investigates further, it would be helpful if you could refresh your current Roon database, test out only importing a fraction of your library, and test for overall stability. The steps to do this are:

Create a Backup of your current Roon Database
Stop RoonServer from running in Nucleus’s WebUI
Navigate to your Nucleus’ Database Location
Find the folder that says “RoonServer”
Rename the “RoonServer” folder to “RoonServer_old”
Restart the RoonServer in the WebUI to generate a new Database
On the Roon Remotes, press “Use another Roon Server” and connect to the new database

After this, go through the motion of setting up a new database (don’t restore from the saved backup) and only add a portion of your local library, and test performance. I realize this isn’t ideal, and a bit tedious, but it will go a long way in helping our team better understand the source of your issue.

We’ll be on standby for your results! Thanks again

Hi @benjamin - this seems to have helped. I did as you said and imported one folder with 8440 tracks and they all imported ok and it seems to be running the background analysis just fine while I am browsing around and playing music.

So if this work ok, what would be next steps and how would I get all my playlists, etc. from my old dB.

Thanks,
Keith

Mike_O_Neill · November 19, 2024, 6:18am

Its not wrong , it just indicates the make up of your library , my guess is a lot of single albums and not many box sets

Best practice with a box set is to set the album name to the same for all CD’s so a Beethoven Piano Sonata set is one album but is 10 disc and 100 tracks . Also sets like ‘x’ Complete Recordings on DG can be 60 CD’s , 7-800 tracks

Hence my album count is low but the Tracks/album id much higher than yours at around 15

Keith_Winand · November 19, 2024, 9:57pm

Hi @benjamin - well, server has been up and running for almost 24 hours with crashing so looks like we know what was going on. thanks.

Now, what are next steps on how to get my info out of the old database and show to proceed with importing the rest of my music library?

Keith

Keith_Winand · November 22, 2024, 4:02pm

Ok, so I haven’t heard from @benjamin or anyone else from support for a few days but here is the status.

I have, once again, created a new instance of the RoonServer folder (renaming the old one) and have imported all my files as opposed to a limited amount.
The files have imported just fine but I did have about 3,000 files that it skipped because it said they were corrupted. This is on top of about 2,000 files from a previous import (not the same files). I have corrected this by converting them to FLAC with dBPoweramp. When I rescan it finds the files and imports them just fine.
But…the server continues to restart randomly when it is doing the background audio analysis. I guess one this is done it will be fine but still not sure I want to keep the Nucleus One as it might not be right for my use. I can always go back to using my Mac Mini M1 where it had no such issues that I am aware of.

Thanks.
