Roon core on Synology NAS crashes

Core Machine (Operating system/System info/Roon build number)

Roon core on Synology NAS RS820+, 16GB RAM

Description Of Issue

  • roon core crashes from time to time, ~1-5 time per day, depending on intense of usage
  • stream stops from one to the next moment and the core is not available anymore
  • Synology DSM does not show any high RAM usage (~25% RAM usage in avg) nor CPU utilization (<10%) at all
  • after ~20min, roon core comes back by themselves

How can I troubleshoot this issue and stabilize the system?
FYI: I’m in the testing period of roon with 12d left, so need to get this fixed soon for further tests of roon.

The RS812+ runs an Intel Atom D2700 CPU - it falls some way short of Roon’s recommended hardware for running the Core (i3 minimum). Under normal use, CPU is relatively low, but some tasks (library indexing, for instance) can push CPU usage to very high percentages on even an i7 or Xeon CPU.

Hi, roon core runs on a RS820+, with a Atom C3538. Sorry for the error. I corrected the model name in the original post. The C3538 has 3 time of the performance of the C2700, which gives more buffer.

I agree that some tasks can force higher load. I’m running performance monitor to see if this is the root cause. However, I can’t see any spikes and the avg cpu load is <20%. Also the roon logs do not report any high CPU load before roon core crashes. I’m continue observing this area.

Hi Jörg,

One further idea I had - is your Roon database on a SSD or a HDD?

hi, the DB is on RAID0 HDD. I’m monitoring IO performance to identify potential bottlenecks here. So far, not a heavy load.

Best, Joerg

To save time for your evaluation, I suggest you install Roon on a computer with SSD for Roon database wired to the Netgear switch, and let it scan the Synology network drive for music.

I agree with Peter, use a proper computer to evaluate Roon, otherwise your pushing your luck without at least an SSD for the database and something fast enough CPU wise to scan and import all your music.

I understand where you are coming from. I do not have computer with the suggested performance available unfortunately. The intent is, to test roon in the targeted constellation.
from a roon user experience I’m testing between the crashes right now …

As described, the NAS has not the lousiest performance and is not highly utilized so that shouldn’t be the bottleneck. Is there any roon logging which can be extended and used to nail down the root cause of the crashes?

try and turn off under settings Library the analysis option might help with some of the cpu usage and need to update database

Hello @Breisgauer, and my apologies for the frustration here. Could you please use the directions found here and send us over a set of logs using a shared Dropbox link.

will do. for the moment it looks like there is an issue with integrating a NW share where my own FLACs are shared. since I removed the folder from ‘storage’ roon gets more stable. I will continue observing this till weekend.

Update: no more crashes since I removed folder integration.

Hi @Breisgauer,

I’m glad to hear that things have stabilized for you. It sounds like there might be a bad/corrupted file (or more than one) in that share that is triggering Roon to crash when it tries to import it. Were you able to send over the logs that @nuwriy mentioned? If you could reproduce this and send us logs after a crash we can get with our QA team and see if we can identify the specific files that are causing this.

Hi @dylan
I will dig into this later and respond to @nuwriy , in case I will continue with Roon. Im in my last two days of the test period.
