Typically I design applications to be as stateless and tolerant of restarts as possible, as they do get restarted during deploys anyhow. That is a minor issue compared to the difficulties around connection restarts and communication between nodes. It is wonderful that Heroku now offers exec, which at least allows using observer and other remote debugging tools. The tooling keeps getting better—but there is no denying that it was designed for Ruby deployment, and working the BEAM has significant production differences.
