Docker hello world не оставляет места на устройстве

Команда docker run hello-world дает мне эту ошибку: System error: write /dev/cgroup/docker/<hash>/cgroup.procs: no space left on device

Это Debian Wheezy с ядром 3.16 из бэкпортов. (ранее обновлялся с squeeze)

/ dev монтируется как devtmpfs размером 10 МБ udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=1019797,mode=755)

Есть ли у докера параметр конфигурации, который мне нужно изменить?

Полный вывод:

$ docker run hello-world
