Just upgraded a dockercontainer (https://github.com/StefanHoutzager/elixir-dev-anywhere-docker) to
Interactive Elixir 1.5.2
At the end of a first day of refactoring / testing I get when I start phoenix.server again:
Setting up watches. Beware: since -r was given, this may take a while!
Failed to watch /stefan/bpm_app; upper limit on inotify watches reached!
Please increase the amount of inotify watches allowed per user via `/proc/sys/fs/inotify/max_user_watches’.
Is this a known bug (is something not properly cleaned up in the os - ubuntu14.04- after stopping phoenix via ctrl-c?) / do I need to configure something?
