Recently formatted my 2011 Mac mini, reinstalled the OS (macOS 10.13.6), and reinstalled the server and copied the old ~/LIbrary/Application Support/Plex Media Server to the new machine.
It is working as it should, except the PMS crashes on more or less a daily basis. Restarting it works fine, but it should of course not crash. Any help appreciated.
Thanks a lot, that will give me something to work on. The machine is constantly being awakened for some reason (Which is why I reset it), so that could explain it.
