Since a month of two my PMS (always the latest version) running on my Nvidia Shield TV, shuts down after a couple of hours. Sometimes it shuts down after an hour, sometimes it takes a couple of hours. It varies and that makes it hard for me to troubleshoot. I've tried a couple of things, like assigning my shield a fixed ip address and re-installing plex, but that doesn't fix the problem.
When it runs, it runs perfectly (remote access and all).
What could be causing this?
