Comment 1 Pierre Ossman cendio 2020-09-16 10:36:02 CEST 
Saw this on an Ubuntu 18.04 system where web access was preventing the system from rebooting in a timely manner.

Got this in the service log:

> Sep 16 08:21:20 ubuntu1804 systemd[1]: Stopping ThinLinc Web Access...
> Sep 16 08:22:50 ubuntu1804 systemd[1]: tlwebaccess.service: State 'stop-sigterm' timed out. Killing.
> Sep 16 08:22:50 ubuntu1804 systemd[1]: tlwebaccess.service: Killing process 17880 (python-thinlinc) with signal SIGKILL.
> Sep 16 08:22:50 ubuntu1804 systemd[1]: tlwebaccess.service: Main process exited, code=killed, status=9/KILL
> Sep 16 08:22:50 ubuntu1804 systemd[1]: tlwebaccess.service: Failed with result 'timeout'.
> Sep 16 08:22:50 ubuntu1804 systemd[1]: Stopped ThinLinc Web Access.

And this in our log:
