Shutdown delayed?

This is a service problem. Some service is halting the shutdown process. And until we know which one, there is nothing to do but speculate. So, how to start solving it? We can start by trying to identify the service. After you experienced one of those prolonged boot situations, be patient.

Unfortunately, I got a null pointer when I tried to find the holdup and the net was full of similar results. But my problem was always in a VM, just the opposite that you report. It wasn't every time either, somewhat random. Does it ever shut down quickly?

Also, I got absolutely no relief from ShutdownWatchdogSec. It seems to do nothing.
