Error message: Waarschuwing 2022-05-08 00:22:11 System 127.0.0.1 Hardware Status Kernel [Hardware Status] NAS out of memory. Started kill process: 31717 “Plex DLNA Serve”. Disable some applications to free up memory, or expand the system memory.

Every day at random times, QNAP shuts down Plex. This is happening since a recent update of the QNAP to version 5.0.0196 build 20200324. I’ve added the logs:

First question…Do you use DNLA, or are you using Plex Clients?

I use Plex server on Qnap en Plex app on Apple TV4.

Then disable DNLA and restart
