Thank you for your anwer.
The rc_debug showed me that the virtualox server are hangs on zfs_stop, 
if i do not enable bastille and reboot all is fine after a shutdown, so 
i think the jail zfs datasets are interfering.
The baremetal server is not waiting for anything just throw the umount 
errors directly.
