Hi all!

I'm not sure if this is known problem or a specific problem with my setup. It is however bugging me, and would appreciate some help! Smile

I run a Debian Wheezy HN with OpenVZ kernel stab108.8-amd64. All my production CTs currently run Debian Wheezy.

When Debian Jessie was released, I started to experiment with Jessie as a CT; both from prebuilt images and also homemade / debootstrapped. Aside from the fact that systemd (which is new in Jessie) is new to me and feels strange Wink, it also appears to have some troubles during shutdown of CT.

Looking at the console of the CT, during shutdown the very last output is:
[  OK  ] Reached target Shutdown.
Sending SIGTERM to remaining processes...
Sending SIGKILL to remaining processes...
Sending SIGKILL to PID 282 (systemd-cgroups).
Unmounting file systems.
Unmounting /dev/mqueue.
All filesystems unmounted.
Halting system.

The SIGKILL of systemd-cgroups is where shutdown gets stuck for 10-15 seconds...

Can anyone shed some lights on this? Is this normal behaviour? It will be painfully slow to shutdown the server if many Jessie CTs are running...
