I'm using emacs for my every day tasks, I started more or less 4 years ago, and now I'm very happy with emacs. maybe I have a lot of plugins working together.
This is my-ruby configuration file I load this while loading the init.el file:

Finally I only have one problematic issue I'm working with a rails project, all works well, rspec, rails console, autocomplete with company ...,
But when I open routes.rb, in 30 seconds Emacs is frozen. I do this:
M-x rvm-activate-correspondenging-ruby
M-x i-rai
then I open the routes.rb file:
and then emacs is broken, I open the debugger,
cat .emacs.d/server/afs
127.0.0.1:50736 6615
Q*"Lj4V[a[X6>KRda1%}K$#JRAR(t`($%8ttyW"g"9L)nob.U8_.XAj@R"tk0oMm%
kill -SIGUSR2 6615
and seems that the problem if a loop that becomes from ruby mode, but I really not know how to follow with it:

ruby-smie--redundant-do-p()
ruby-smie--backward-token()

since the last three functions are from:
/usr/local/Cellar/emacs/25.2/share/emacs/25.2/lisp/progmodes
ruby-mode.el.gz
I do not know how to proceed from here. any advice will be appreciated. this only happens with routes.rb file. for example if now I close the buffer with routes.rb it will work again well
