Docker socket crash after stack up

I trying to deploy docker stack, that includes my development environment. But in random cases I have next error:

failed to create service < service_name >: Cannot connect to the
Docker daemon at unix:///var/run/docker.sock. Is the docker daemon
running?

Next I restart docker daemon. Sometimes it requires to kill docker processes and shims. I deleting old stack and build again. Some times docker successfully finishes build, but socket crashes on the starting stage.

Also all containers work properly when I starting it in regular mode, without swarm or stack. It is not work exactly inside swarm.

I have used next command to build:

$ docker stack deploy dev-env-stc -c docker-compose.yml

Environment run in Antergos Linux(Arch).

Layout is like at the diagram

Nginx container and docker networks created using commands:
