DVR Crash on Synology 918+

Every 2 or 3 days I find that the DVR has crashed on my Synology 918+. I can most times restart this from the Package Center occasionally though I need to restart the Synology device completely.

Here's part of the log file after the crash which continues with more goroutine statements.

Any help appreciated.

I think I've submitted the logs. Are you able to confirm?

Got it thanks

Could you try submitting again? Something went wrong in the submission process.

I’ve re-submitted the logs. Looks like it worked this time.

My best guess is you're running into memory issues on your system.

Can you follow the instructions here to test your RAM?

I switched out the ram module in my Synology over the weekend and so far I have not encountered any issues. Many thanks!
