Hi all,

Im am running a ubuntu 12.04 guest on an ubuntu 12.04 host (see
vserver-info below).

The vservers are running fine, except that stopping a vserver causes a
timeout:

root@kmux-host:~/kmux/kmux/branches/kmuxNG/kmux-generate/config# vserver
--verbose kmux-fs stop
A timeout occured while waiting for the vserver to finish and it will
be killed by sending a SIGKILL signal. The following process list
might be useful for finding out the reason of this behavior:

----------------------------------------------------------------------
  7951 1022 kmux-fs ? Ss 0:00 /sbin/init
----------------------------------------------------------------------

Well, I tried to get the root-cause of this problem, but with no luck.
Disabling console output of upstart services and enabling upstart
--debug did not help in any respect.

Are the any further hints?
