Looking a bit more on the internet i found this:
https://blog.phusion.nl/2015/01/20/docker-and-the-pid-1-zombie-reaping-problem/
which seems to describe exactly the problem that you are experiencing. The
erlang vm is not built to run as the pid 1 process, even with my new
changes in the master branch this will still be a problem as instead of
missing out on exit_status messages you will have a system full of zombie
processes.
