Docker exec -it <container> bash completely hangs on any container. Docker version 1.12.0. Help?!

General

I’m running several containers and I can’t exec -it into any of them. As soon as I do docker exec -it bash the CLI hangs completely, I cannot even Ctrl+C. I’m really frustrated with this. Any Ideas?
