[HotLoader] starting WS server (ws://0.0.0.0:8082) - starts many times

[rafath]

rails: 5.0.1
mac os (rvm, ruby 2.4)
using puma (standard command rails s)
Each time I browse any page, with or without react component, in my log console I'm getting many many entries (about 67)

What is cause of this?

It seems, that for every scss or js file - Im getting each hit, is this normal? (in dev env)

@rafath Seems to be not normal. I have the same problem after running the dev server for a while, after a restart, problem is gone. Pretty annoying...

@rafath I just realized that a new websocket connection is opened for each JSON XHR request. This might be the cause of the massive number of websockets and subsequent multiple reloading for a single change

This is happening to us as well. Here is a screenshot of our logs: https://www.dropbox.com/s/tgcaffdqo208d7c/Screenshot%202017-08-07%2017.33.44.png?dl=0

It has significantly slowed down load times on dev mode.

@rafath @phillipp I opened a pull request with the fix that solved this issue for me (#19)
