Description of Issue

Roon ARC caused the Roon Core to crash.

Everything is working fine with Roon at home, but as soon as the ROON ARC connects to the Roon Core, after playing about two to three songs, the Roon Core program freezes.
The Roon Core needs to be restarted in order to function normally. I have tried reinstalling it on both my computer and smartphone, but the issue remains unresolved.

I have the same problem. Watching this issue.

Hi @fver and @lin_hsiao_yuan,

Thank you for the reports. The team is actively investigating this issue.

Are you able to provide track names for an example of when this occurs? We want to investigate the possibility that requests associated with these track files (unicode characters, metadata, etc.) are causing a feedback response in the Core. Track names will help us identify the moment in logging when this occurs. If these are local tracks in particular, you can also upload one here for our team to investigate: Media Uploader (Tech Support)

Thank you for your patience. Weā€™ll follow up shortly with next steps.

As a workaround, try resetting your Roon database. Itā€™s possible this may clear any cached content that might be involved with the crash. If you create a reliable Backup this wonā€™t affect any Library content or Zone customization, although it may require some time to reanalyze your library on reloading Roon:

  • Create a Backup of your current database
  • Exit out of Roon
  • Navigate to your Roon Database Location
  • Find the folder that says ā€œRoonā€
  • Rename the ā€œRoonā€ folder to ā€œRoon_oldā€
  • Reinstall the Roon App from our Downloads Page to generate a new Roon folder
  • Verify if the issue persists on a fresh database before restoring the backup

Description of Issue

It appears that ARC is stopping the core from sending to network endpoints at random times.
If I do not use ARC everything if fine.
When ARC changes songs or looks up something in the library (browsing albums, playlists or such) there is a chance that it will kill playback to network connected endpoints either hardwired or Wi-Fi.
The only way to get anything to play again or to get ARC to connect again is to restart the core.
Once the core is restarted, everything goes back to working normally. No reboot of Windows needed to resume normal operations.
This occurs randomly and has been happening for about 2 and a half weeks now.
It does not matter if ARC is running from home Wi-Fi or the phone carriers network.
The upgrade this week did not change this behavior.
I have reinstalled ARC several times.
I have uninstalled and installed Roon client and Roon server on the machine running the core.
The Windows machine running the core has been rebooted many times.
Database seems to be fine, It backs up without any issues.
I have uploaded my server logs with the file name ā€˜(moderated)@gmail.com.zipā€™.

Thank you for looking into this issue.

Hi @James_Raver,

After investigating your report and associated diagnostics, weā€™ve merged your report into an associated topic thread that we believe shares an underlying cause. Please see our response above to @lin_hsiao_yuan for additional details; the team will continue to narrow down the cause and respond here when we have a fix in place or next steps available.

I moved over to a ROCK setup and am not having any issues with ARC crashing the core now.

Thanks for the update, @James_Raver. Weā€™re still investigating the original issue but glad to hear youā€™re not encountering any symptoms. Please keep us posted if performance declines for any reason.

ARC has been pretty stable for me for months now, but Iā€™ve just moved house (so my external IP has changed) and now playing ARC crashes Core when I hit play externally. Playing from ARC within my wifi signal works fine though.

Donā€™t know if the cause is similar to that above, but my result is the sameā€¦ Core is responsive in terms of
appearing on the network and letting the remotes talk to it, but it wonā€™t display or play any media from that point onwards, and requires a reboot to resolveā€¦

Build 1303 has been pretty stable so far.
Iā€™ve even had the pleasure of taking ARC abroad for our summer holiday and it worked perfectly.

This morning, I tried ARC back in my home country - and itā€™s back to the poor connection and crashing the core routine.

Have the same problem. After listening a few albums Roon Core stops responding. Clients canā€™t retrieve data from core and their interfaces looks like messed. This problem appears from ARC release.
I use Roon on Fedora 37 on AMD platform

this is still happening at least once a week

I have the same problem. After a short while playing from ARC, Roon core needs to be stopped-restarted.

The same here: Roon is playing nicely, but when I leave the house and use ARC, after an arbitrary number of songs, ARC reports it has a poor connection. I then have to restart my Roon Core and Iā€™m back on track untill it crashes again.
My Set Up: A Mac Mini 2018 as Roon Core, Iphone 12 with IOS 17 (but it started with IOS 16). Some 72K of numbers on my hard drive (mix of FLAC and mp3ā€™s mostly) and a Qobuz subscription.

About a week or so after I made my post above, all of my problems went away for the remainder of August and all of September.

Unfortunately Iā€™ve recently had the problem come back.l with numerous crashes requiring a reboot in October. I dont know if it is a factor but about a month ago I enabled IPv6 on my router (but I also have a static IPv4 so Iā€™m not dependent on IPv6 for anything to work inbound).

Good luck getting any help from so called ā€œsupportā€. The same issue has been discussed at length in this thread, without resolution: Roon & ARC have become incredibly unreliable for me - what is going on?

Iā€™m running Roon core on Synology DS923+ NAS with 32GB of RAM. Roon DB is on NVME SSD.
Running Roon core with RoonOnNas package.

Having the same issues discussed here. Core crashes after 2-10 songs if played with ARC. No problems with Roon for Windows or Roon remote for Android.

When core crashes roon Arc starts showing connection problems and both remotes do not connect anymore.

Is there any info I could provide to contribute to the solution to this problem?

I also have this problem. Roon Core on iMac (2020) i7, 64GB RAM. Storage on NAS. When I use Roon ARC, it end up crashing the Roon Core after some songs were played. This problem is there for some months now.

Managed to fix my problem with core crashing when using Roon ARC. All I did was: disabled port forwarding on my Asus router (running Asuswrt Merlin with UPnP enabled).

It was my mistake: running UPnP enabled together with port forwarding as it is not recommended having both of them enabled at the same time for various reasons.
Also, port trigger should not be enabled together with UPnP or port forwarding.

Ideally only one of these should be enabled at any one time: port forward, port trigger, UPnP.

Iā€™m not sure how this caused core crashes for me. There should have been connectivity error messages at the most not core crashes.
Anyway, just hope my discovery will help someone else as well.

Think iā€™m suffering the same - ARC will work for a while and then stop talking to the core. Using the normal Roon app shows all the stats etc, but just the spinner underneath - no ability to play anything.

Rebooting the server gets it all working again - but i only seem to be able to do this manually, is there any way of restarting via the app?
