@cyphar Any idea on this issue? The same runc command works when running from terminal.

This is a little odd, but I feel it might be because the cgroup has processes still left in it (which is odd, because runc creates its own cgroups by default). Is there anything odd about your configuration?

This is where the error is coming from.

// RemovePaths iterates over the provided paths removing them.
// We trying to remove all paths five times with increasing delay between tries.
// If after all there are not removed cgroups - appropriate error will be
// returned.
func RemovePaths(paths map[string]string) (err error) {
	delay := 10 * time.Millisecond
	for i := 0; i < 5; i++ {
		if i != 0 {
			time.Sleep(delay)
			delay *= 2
		}
		for s, p := range paths {
			os.RemoveAll(p)
			// TODO: here probably should be logging
			_, err := os.Stat(p)
			// We need this strange way of checking cgroups existence because
			// RemoveAll almost always returns error, even on already removed
			// cgroups
			if os.IsNotExist(err) {
				delete(paths, s)
			}
		}
		if len(paths) == 0 {
			return nil
		}
	}
	return fmt.Errorf("Failed to remove paths: %v", paths)
}

@cyphar this was due to an old kernel issue. The system on which my colleague tried was having 3.10, once upgraded the error went away, had to disable tty as per #202. I'm closing this issue. Thanks for the help.
