QNAP TS-453B Random Restarts

Plex Media Server NAS & Devices

@Jonathan-458 Thanks for the update - I had a very similar experience with QNAP… just passing the blame to Plex.

If you guys can update once @ChuckPa has had a look at the diagnostic data, that would be much appreciated!

Thanks

@DonCaliOni

We went through the diagnostic data (kernel panic logs)

  1. QNAP kernel panic on the i915.
  2. It was passed a null pointer when the transcoder was running
  3. Program faults should NEVER panic a kernel. It should kill the process.
  4. Conclusion: Kernel Bug for QNAP to fix or bad hardware
  5. – I had an i7-7700 do the same thing which QNAP replaced under warranty. Never had a problem since

Evidence of kernel bug

Pfff they are really fighting me on this, i asked them to share exact data that supports their claim.

@DonCaliOni,
When you generate diagnostics via QNAP Helpdesk a zip file is downloaded to your computer, open it and navigate to [filename]\sys\fs\pstore and there should be a file named “console-ramoops-0” can you please check if you find similarities.

Yep, I have got something very similar:

For me it ultimately turned out to be a memory issue. I RMA’d my 8GB to Crucial and they sent over a new pair. It has not crashed or rebooted since replacing the memory. Memtest86 did not report any faults with it, but sent it in anyway.

@UncleBabyBilly I actually got a new unit TS-453D but it still crashed once. However, it’s been fine for a month or two.

I reckon a Plex update must have solved the issue, which coincided with you changing the RAM, as I tried switching to original QNAP RAM, and a whole new unit, with both cases still resulting in a crash.

Small update, i updated to 4.5.4.1723 build 20210708 and experienced no unexpected shutdowns with the Crucial Ram for now.

Since QNAP only want’s to change the unit if the issue occurs with QNAP RAM, i’ve switched back to QNAP/ADATA RAM and back to the waiting game.
