[systemd-devel] Randomly on shutdown, stop timeout for user at .service (repeated report, different user)

[Toms Seisums]

It appears that history repeats itself.

Once (July 2013) a similar issue was reported here, by different user:
http://lists.freedesktop.org/archives/systemd-devel/2013-July/012283.html

I'm also using Arch Linux, systemd-207, linux-3.11.2.

On shutdown and reboot, user at 0.service occasionally freezes my system until
it times out and gets killed.

Steps to reproduce:
1) Boot
2) Login
3) Execute either systemctl reboot or reboot or shutdown -h now or whatever.

I've went through the steps here, to get a proper shutdown log:
http://freedesktop.org/wiki/Software/systemd/Debugging/#shutdowncompleteseventually

And, the shutdown log can be found here: http://pastebin.com/wbr04AQw

The actual lines related to issue:

#2223 [   74.387130] systemd[1]: Got D-Bus request:
org.freedesktop.DBus.Local.Disconnected() on /org/freedesktop/DBus/Local
#2224 [  163.814925] systemd[1]: user at 0.service stopping timed out. Killing.

#2226 [  163.816063] systemd[1]: Received SIGCHLD from PID 326 (systemd).
#2227 [  163.816093] systemd[1]: Got SIGCHLD for process 326 (systemd)
#2228 [  163.816153] systemd[1]: Child 326 died (code=killed, status=9/KILL)
#2229 [  163.816158] systemd[1]: Child 326 belongs to user at 0.service
#2230 [  163.816171] systemd[1]: user at 0.service: main process exited,
code=killed, status=9/KILL
#2231 [  163.816183] systemd[1]: user at 0.service changed stop-sigkill ->
failed

I currently haven't found out a pattern for this. I have attempted to quit
some processes before initiating the shutdown/reboot, but the result is
random.

About 95% of shutdowns/reboots it will be a long one.
3% it will be noticeably longer than the quickest one, but shorter than the
above one.
Remaining 2%, the shutdown will be very quick.

It also happens if I get to log in console screen and Ctrl + Alt + Del,
like, I perform an ASAP shutdown after boot.

In case anything more is needed, please ask.
