[Pkg-systemd-maintainers] Bug#739887: systemd cannot stop samba (hangs forever)

[Adrian Knoth]

Package: systemd
Version: 204-7
Severity: normal

Hi!

Disclaimer: This may well be a bug in the samba package, but since the
bug can only be triggered in conjunction with systemd, I file it against
systemd. Feel free to reassign.

Trying to stop samba via

   # systemctl stop samba

hangs forever (or at least longer than I have patience). This means
shutting down the machine hangs, too.

Surprisingly, using

   /etc/init.d/samba stop

works:

chopin:/home/adi# /etc/init.d/samba stop
[ ok ] Stopping samba-ad-dc (via systemctl): samba-ad-dc.service.
[ ok ] Stopping smbd (via systemctl): smbd.service.
[ ok ] Stopping nmbd (via systemctl): nmbd.service.

[hangs, so let's switch to another  terminal]
