Cannot remove dead docker containers. Storage driver: btrfs

问题

I am having trouble removing dead containers. When I try to remove container I get:

$ docker rm -f d1dd3082f7bb
Error response from daemon: Unable to remove filesystem for d1dd3082f7bbfc2310e497d0af47d51a8ca4e6e90a0d565a85d033f96a12325f: remove /var/lib/docker/containers/d1dd3082f7bbfc2310e497d0af47d51a8ca4e6e90a0d565a85d033f96a12325f/shm: device or resource busy

Have never encountered such problem before. Some information about current setup:

How can I safely remove them?

Forgot to mention that these containers are managed by docker swarm and compose.

$ docker ps -a

Adding docker inspect of dead container, inspect output

$ docker inspect 4a1193af7710

grep d1dd3082f7bbfc2310e497d0af47d51a8ca4e6e90a0d565a85d033f96a12325f /proc/*/mountinfo

then find the pid of d1dd3082f7bbfc2310e497d0af47d51a8ca4e6e90a0d565a85d033f96a12325f and kill it
