I’ve been playing with Ubuntu 17.04 in a VMware VM and pulled in one of my Phoenix projects (Phoenix 1.3-rc, Elixir 1.4.2, Erlang 19.2.1). It pulls the deps fine, compiles fine, and runs the tests fine. But when I load a Phoenix page in my browser it recompiles the whole application and gives a bunch of warnings about redefining module. It does this over and over for every page load and, of course, it’s super slow because of that.

warning: redefining module Molly.Integration.Server (current version loaded from _build/dev/lib/molly/ebin/Elixir.Molly.Integration.Server.beam)
  lib/molly/integration/server.ex:1

Has anyone seen anything like this? Thanks!
