Vanilla 12.10 Ubuntu server:
root@atlas01:~# sudo lxc-version
lxc version: 0.8.0-rc1
I may very well have accidentally tried to start the same container twice, I
think I fat-fingered something just before encountering the issue, and I've
never had it happen on any of our other boxes. Anyway, it's of no real
consequence to me now as I cleared it easily enough, but I thought it worth
mentioning.

Is this by chance an older version of lxc? It sounds like there were later
attempts to start testdb1, and so
/sys/fs/cgroup/freezer/lxc/testdb1 got renamed to deadXXXXX, then the later
attempt failed, so
/sys/fs/cgroup/freezer/lxc/testdb1 ended up not existing.
Note that that behavior no longer exists in very recent lxc.
Rather, the second attempt would use
/sys/fs/cgroup/freezer/lxc/testdb1-2, and lxc-list would ask the container
monitor for the right cgroup path, preventing this -ENOENT. At least that's
the theory :)
