You were ABSOLUTELY right, Karl! Thank you, problem was solved! I'll try to describe it in details...We get two instances of operating system -- one is host OS, and another is LXC-container. And they have shared /dev (via bind-mount). Both of them have their own /sbin/init running. I far as I understood, init process recreates /dev/initctl pipe in case it can't find it OR it doesn't belong to it -- approximately every two seconds.
So, half of time we have host's initctl in /dev -- and another half of time we have container's initctl there. And if we issue shutdown command (from host or from container, no matter actually) -- it can end in two equiprobable ways:
1) host goes down (if we get host's initctl in /dev that moment); 2) container goes down (if we get container's initctl in /dev that moment). 10.09.2012 13:36, Karl E. Jorgensen wrote:

When I enter the container (via lxc-console command) and issue shutdown command inside the container -- master host goes down. It happens if I issue "shutdown -r", "shutdown -h" or just "shutdown" commands. It happens not every time -- in some cases behavior is correct: shutdown command doesn't affect master host and container just goes down.Have you got /dev bind-mounted to the container? If so, that could explain it, as they will end up sharing /dev/initctl - which controls init, and thus controls runlevels and shutdown...
