I am running a headless Ubuntu 18.04.2 LTS Media Server. I upgraded it many moons ago from 16 and the server has been rock solid for a very long time. In the past month or so, the machine becomes completely unresponsive. IE No pings, SSH and if I go to the console (Running in ESXI) I can see some CUPS errors on screen but also can not get it to respond to direct keyboard inputs. The only option left is to reset the machine via VMWare.

If I look in /var/log/syslog it gives no real clues. In /var/log/kern.log I see a massive gap in logs from when I reset the server:

If anybody can assist, that would be great.

  • I don't know what you mean by part number, but this is my own local VM on my own hardware in my house.
