That error message is harmless. I’m not sure what’s going on there but this sounds like a hardware issue. The NAS itself rebooting is quite worrying. Can you post this in the PMS section?

I think since the new Plex app does not transcode into hardware, your computing power is insufficient and the CPU is overwhelmed and the Plex server hangs up!?
