lxc container shutdown on ubuntu make the system stop to work

I have a lxc container that works like a php and mysql server. When I do:
sudo lxc-shutdown -n [name of container], all my system stops to work. The
only thing I can do is turn off the computer directly on the button,
because the ubuntu don't respond more any command after the shutdown
process of the lxc container. This problem became boring, because all the
time that I need turn off my lxc container my computer stops to wrok too.
How can I fix this issues?
Thanks
The version of my ubuntu is 13.04 I created this container in a simple
way: lxc-create -n ubuntu-server, and I started to use.
The following is my config file of the container:
lxc.network.type = veth
lxc.network.hwaddr = 00:16:3e:e0:00:ee
lxc.network.link = lxcbr0
lxc.network.flags = up
lxc.rootfs = /var/lib/lxc/ubuntu-server/rootfs
lxc.mount = /var/lib/lxc/ubuntu-server/fstab
lxc.pivotdir = lxc_putold
lxc.devttydir = lxc
lxc.tty = 4
lxc.pts = 1024
lxc.utsname = ubuntu-server
lxc.arch = amd64
lxc.cap.drop = sys_module mac_admin mac_override
