systemd shutdown "session-c1.scope: Stopping timed out. Killing."

I've had an issue for ages that I cannot reproduce deterministically.
Once in 10-15 shutdowns systemd hangs (by default for 90 secs) then finally outputs a message in the spirit of the following before shutting down:

... session-c1.scope: Stopping timed out. Killing.

I produced a log following these instructions: https://freedesktop.org/wiki/Software/s … /#index2h1

Here are some highlights:

[ 3202.887803] systemd[1]: Received SIGCHLD from PID 917 (awesome).
[ 3202.887843] systemd[1]: Child 917 (awesome) died (code=exited, status=1/FAILURE)

[ 3212.551751] systemd[1]: session-c1.scope: Stopping timed out. Killing.
[ 3212.551902] systemd[1]: session-c1.scope: Killing process 1213 (emacs) with signal SIGKILL.
[ 3212.552001] systemd[1]: session-c1.scope changed stop-sigterm -> stop-sigkill

As the log shows, I use LXDM, Awesome and Emacs (which is forked as a daemon).

Any lead?

It is back!
The annoying 90sec delay irregulary on shutdown/reboot with message
'A stop job is running for session c1...' since ca. a week.

Everything updated today.

Kernel: 4.11.5-1-ARCH
DE: openbox / lxqt

I think it might have been something to do with lxqt-panel.desktop or menu-cached?

# journalctl -b -1 (partial)

.
.
.
  login[464]: pam_unix(login:session): session closed for user XXX
  login[464]: pam_systemd(login:session): Failed to release session: Connection reset by peer
  systemd-logind[402]: Failed to abandon session scope, ignoring: Transport endpoint is not connected
  systemd[1]: Stopped Getty on tty1.
  systemd[1]: Removed slice system-getty.slice.
  lxqt-session[1]: lxqt-session: "Module 'lxqt-panel.desktop' won't terminate ... killing."
  lxqt-session[1]: QProcess: Destroyed while process ("lxqt-panel") is still running.
  lxqt-session[1]: The X11 connection broke: I/O error (code 1)
  systemd[1]: session-c1.scope: Stopping timed out. Killing.
  systemd[1]: session-c1.scope: Killing process 800 (menu-cached) with signal SIGKILL.
  systemd[1]: Stopped Session c1 of user XXX.
  systemd[1]: session-c1.scope: Unit entered failed state.
  systemd[1]: Removed slice User Slice of .
  systemd[1]: Stopping Login Service...
.
.
.

The number behind 'session c#' changes sometimes.

Can anyone tell me how to get rid of this 'A stop job is running...' again?

Moving to Applications and DEs.

Edit: Merging with an existing thread.

Note: roxosulaliwe's thread has been merged with this thread.

@roxosulaliwe: You can reduce the timeout in /etc/systemd/system.conf, variable DefaultTimeoutStopSec.

I am trying to connect the dots of people experiencing more or less the same issue.
See my bug report and comments of others:

lxqt-panel: reboot and shutdown takes a long time

If you feel you have the same issue, and you believe lxqt is the issue, this might be a place to start.

I am not using lxqt, not mentioning the panel. I do use LXDM however. I'll try without it from now on and report back in a week or so.

OK, that wasn't it. LXDM is not the culprit (or at least not the only one).
