Roon Server Crashes and Unresponsive Remote after Migrating to Nucleus One (ref#O37I9L)

What’s happening?

How can we help?

· I am experiencing freezes or crashes

Describe the issue

Recently migrated my Roon Server from a Windows machine to a brand new Nucleus One. Super happy with the transition, except that I get Roon Server crashes every now and then.
Just yesterday, one of my family members queued up a song to play and the remote went unresponsive and said "waiting for your roon server". I've went into the ROCK web interface and noticed that the roon server has restarted itself (all other uptime metrics went back a few days) with no apparent reason. Checked the logs but couldn't make out anything on my own.

Describe your network setup

My nuclues is connected directly via cable to my router. The zone for which the song was queued up and caused a crash is connected via cable to a mesh node which is wirelessly connected to the router.

Hey @grzlybear,

Thanks for taking the time to write in and share your report! Sorry to hear about you’re issues with your Nucleus and audio playback.

Can you share a screenshot of the webUI of the Nucleus?

Which remote specifically? From your account information, we’re seeing a few Android devices, was there another device you were using?

What happens if you set up a second hardwire connection using the remote device, and connect it directly to your rourter, similarly to your Nucleus? I understand this may not be a long-term solution, but it’d be good to better ensure your network is as stable as possible.

Let us know the next time this happens specifically, and we’ll enable diagnostics for your Nucleus to investigate further. Thank you! :raised_hands:

Hey Brian, thanks for getting back to me.

Here is a screenshot (from now) of the Nucleus Web UI:

The remote in question is an amazon fire hd tablet - it’s the only one with an active profile named “Kids”.

I don’t have an option to connect that zone directly to the router unfortunately. Different rooms and too big of a distance.

I will say that I have not experienced any disconnects of other devices from other connected devices on that mesh node. First thing I suspected was obviously the WIFI but router logs have not shown disconnects and signal strength to the node is lableled as “Excellent” by the internal router software.

Moreover, I was surprised to see that the server restarted itself (not the entire ROCK or hardware) - just the roon software server component.

I’ve kept a dump of the logs that I collected after doing some debugging. Would it be helpful to share them with you?

@grzlybear yes that would be helpful. You can upload them here.

Hi! I uploaded the files.

I’ll note that I haven’t experienced any similar crashes since the last version update a few days ago.

Thanks for getting the files to us. It looks like you only uploaded two log files. There should be 20 of them. Can you upload the rest? In the meantime I will look at the file you sent.

That’s a good sign! Hopefully that continues to be the case.

Just happened again

I’m uploading the logs and this time with all 20 files

Hey @grzlybear,

Thanks for taking the time to share additional logging.

As a next step, lets see if refreshing your RAATSever database may help.

You can generate a new RAATServer instance on your device by following these instructions, but please be aware that this will reset your Roon Settings → Audio Tab to factory settings and I would advise making a backup of any custom DSP settings you have:

  • Create a Backup of your current Roon Database
  • Stop RoonServer from running in Nucleus’s WebUI
  • Navigate to your Roon’s Database Location
  • Find the folder that says “RAATServer”
  • Rename the “RAATServer” folder to “RAATServer_old”
  • Restart the RoonServer in the WebUI to generate a new RAATServer

We’ll be on standby for your results! :raised_hands:

Thanks Benjamin!

I refreshed the RAAT server, and I will continue monitoring in the upcoming days.

Great we look forward to hearing if there are any further issues.

Pretty sure it happened again, but I wasn’t there to experience it.

Hey @grzlybear,

Thanks for the update! We were able to review another diagnostic report from your Nucleus, but didn’t see any obvious issues based on the screenshot you shared above.

We’re sorry for not being able to pinpoint the cause of your crashes so far! As a next step (if you haven’t yet) could you go ahead and reinstall the OS via the webUI and see if your crashing continues?

We’ll be on standby for your results! :+1:

Sure thing Benjamin, I’ve reinstalled the system.

Hi @grzlybear,
Have you had any crashing issues since reinstalling?
