Did this coincide with an update to either Ubuntu or Roon? I note that your Ubuntu install doesn’t have the latest binaries and fixes too (you’re probably not running HWE.)

Steven_Neighorn · March 21, 2019, 7:21pm

Hello Martin, thank you for the response.

I am not running HWE.

I installed the “1.6 build 401” on or shortly after Feb 20th. I had an alert on the main Roon screen and
followed instructions for update. I am sorry to say that I don’t know if the crashes started then or
sometime after. I have improved the logging notifications on the system and started seeing the
crash reports. While I do apply Ubuntu 16 patches as they come out via “apt” the server itself has not been rebooted in a few months.

Do you recommend HWE for U16.04 as a next step?

Martin_Webster · March 21, 2019, 7:32pm

First I’d try a reboot, then consider 16.04.5. I use HWE since it keeps my system up-to-date, particularly for kernel. This is particularly useful if newer applications need functionality in newer kernels.

I’m running 18.04 now, but you should be able to execute the following to enable HWE.

sudo apt install --install-recommends linux-generic-hwe-16.04

Steven_Neighorn · March 21, 2019, 11:42pm

Thanks again Martin. I will give this a try ASAP. I really appreciate your help.

Steven_Neighorn · March 25, 2019, 10:45pm

I did the HWE install, and the reboot, and sadly the problem has not gone away.

Here is the latest crash (top and bottom)

Hello @Steven_Neighorn,

Are you by any chance running Emby on the Ubuntu Core? I have seen an issue with having both Roon and Emby at the same time as documented in this thread (Roon Server on Linux core dump on startup).

– Noris

Steven_Neighorn · March 26, 2019, 5:13pm

Thank you Noris,

I am not running emby. I do run Plex on the same server. I am not using containers. The process list for roon and plex follows:

(notice that “start.sh” was run on March 22nd but RoonAppliance and processreaper and RAATServer all have start time stamps of 9:09AM (about an hour ago), since those are the programs that get restarted after each ABRT).

Martin_Webster · March 26, 2019, 6:55pm

Are you running Ubuntu Server or Desktop? Need to establish if you are running other Mono/ .Net applications on your system.

Steven_Neighorn · March 26, 2019, 9:55pm

Thanks again Martin. I am running the Ubuntu Server. This is on a Dell 2U R720xd. No X11 stuff, no mono apps, and no .Net apps. I believe the crashes started after the upgrade to 1.6 but I don’t know if it was 1.6 and then some ubuntu patches, or just 1.6 upgrade. I am sorry to say that I wasn’t paying
close enough attention to it. Roon is so good at restarting that I didn’t notice the crash info until I increased the level of logging and started seeing the “start.sh” output in a logcheck email.

noris · March 28, 2019, 1:36am

Hi @Steven_Neighorn,

I have moved your post over to the #support category for better tracking here. Can I please ask you to perform a test here? If you disable all of your Watched Folders in Roon and use Roon with just streaming service(s), does the same issue occur?

Thanks,
Noris

Steven_Neighorn · March 28, 2019, 6:15pm

Thank you Noris,

I have disabled the folder Roon was watching using Settings/Storage/Folders. The folder is now listed in red as “disabled”. I will update you with status. The last crash was at 8:23AM this morning, and it is now 11:15AM.

I now have 50 albums and 738 tracks, which are all from Tidal.

Steven_Neighorn · March 29, 2019, 11:54pm

Sorry to say the crashes continue. Maybe not as often but the roon services have crashed twice in the past 24 hours. Same exact errors as before. Let me know if you need the full text of the error or if you have other ideas.

noris · April 1, 2019, 8:27pm

Hello @Steven_Neighorn,

I have gone ahead and enabled diagnostics mode for your Core and what this action does is automatically upload a set of diagnostics to our servers for analysis. The report just arrived, and from what I can tell the storage locations are still active.

I am thinking that this crash might be media related, so as a test I was hoping that we can remove this variable from the equation. At the start of the log traces I am seeing these two media folders appear:

/mnt/media/music/0-9/10,000 Maniacs/Our Time in Eden/10,000 Maniacs - Our Time in Eden
/mnt/media/music/0-9/22 Brides/Beaker/22 Brides - Beaker

Can you double check to make sure that all of your storage folders including these two are disabled as a test as to rule out possible media-related issues?

Thanks,
Noris

Steven_Neighorn · April 1, 2019, 8:54pm

Hi Norris,

I had disabled the media, and just had the tidal account active. The server kept crashing. So I re-enabled, but I will turn the media watch folder OFF again so you can debug. I sent the “sorry to say” msg 3 days ago. I will turn that off right now. Thank you.

Steven_Neighorn · April 1, 2019, 8:56pm

OK, the /mnt/media folder is disabled. The only music the server sees now is my stuff from Tidal. 50 albums and 738 tracks. Please confirm that you see this too and let me know what else you need. I will
leave the media mnt disabled until you tell me otherwise.

noris · April 1, 2019, 9:34pm

Hello @Steven_Neighorn,

Thanks for disabling that location. Yes, I do see that it shows as offline in the diagnostics now.

Please reboot your Core and run this configuration for a day or two and note the exact local time (e.g. 5:33PM) of the next crash with the media locates turned off.

I will then take a look around your reported timestamp to see if there are any traces that could indicate the cause for the behavior.

Thanks,
Noris

noris · April 3, 2019, 3:23pm

Hello @Steven_Neighorn,

Thanks for submitting that info and for trying the setup with storage disabled. I can confirm that the diagnostics report reached out servers and I have asked QA to take a look to see if they can identify any possible sources of this issue. I appreciate your patience until I hear back regarding the analysis.

Thanks,
Noris

noris · April 4, 2019, 6:57pm

Hello @Steven_Neighorn,

I just heard back from QA and they noted that this issue might be due to your networking interfaces on the Core. They have seen similar cases previously where turning off all except one network interfaces resolved the issue. Can you give this a try on your end and let me know if this changes anything with regards to the issue?

Thanks,
Noris
