docker-compose eventually quits with error

[aaronjensen]

If I docker-compose up, things seem to work, then after a minute or so I get:

ERROR: compose.cli.main.main: Couldn't connect to Docker daemon - you might need to run `docker-machine start default`.

$ docker -v
Docker version 1.10.3, build 20f81dd

$ docker-compose -v
docker-compose version 1.6.2, build 4d72027

$ dinghy status
   VM: running
  NFS: running
 FSEV: running
PROXY: running

Your environment variables are already set correctly.

I can reattach with docker-compose up as all of the containers are still running, I'll just lose connection again.

I believe this is the issue: docker/compose#3106
