Vero 4k crashing intermittently when skipping in video

Hello, for a while I’ve had a problem on my Vero 4k where when I skip either forward or backwards in a video, OSMC intermittently crashes and the device eventually reboots on its own. I’m able to get back to the same video and watch normally after the reboot. This does not appear to me to be related to a specific file, and seems to me that it happens more often when the device has been on for a while, whereas it seems to be harder to trigger on a fresh reboot. FWIW, I’m running through a Denon AVR-X2300W to an Epson 5050UB. The media is hosted on a NAS and mounted via fstab.

I did not have debug logs enabled when this happened after the device was up for ~7 days, however after enabling debug mode and rebooting, i was able to get a similar crash behavior to happen. In the logs I noticed CAESinkALSA - snd_pcm_writei(-32) Broken pipe - trying to recover.

Any help or pointers would be appreciated, thanks!

Do you see the frowning face? Does just Kodi crash or the whole box reboot?

Is this only happening when playing content with a TrueHD track?

Thanks for the quick responses! I had to leave for a few days but will respond back when I’m back home and can confirm.

You can use https://videosam.pl to drag and drop a file and give us MediaInfo output if not sure.

I confirmed this is happening when playing EAC3, so it is not just limited to TrueHD. I checked last and the system is not rebooting, it’s just the frowning face and osmc restarting.

Shouldn’t happen with anything over than TrueHD. Can you post some logs to show that?

Sam

Sure! See new paste @ https://paste.osmc.tv/bumimavule. I downloaded The World in HDR.mkv from https://kodi.wiki/view/Samples#4K_.28UltraHD.29 which is VP9 and Vorbis audio. Similar behavior; I skipped around a bunch to try to re-create the problem and it crashed kodi again.

Can you try playing this file from local storage?

Tried from local sd card storage just now; unable to reproduce.

Okay, can you tell us more about the device you are streaming from?

It’s a Synology DS418 (link).

Not sure how relevant it is, but here’s some iperf data from the Vero 4k to the NAS:

Had this happen again so i went ahead and enabled component logging for the audio and video related components and triggered this again. Also captured the sudo dmesg output. Looks like there was an OOM issue?

Latest logs including the audio/video components (i had to extract just the last couple minutes because the log file was too large to upload apparently): https://paste.osmc.tv/urumowihuz

relevant dmesg info:
