Normaly, I don't need to restart rails s when I modify something in controller. But now it doesn't longer work. If I only want to add a "puts" line, I need to kill the server, kill Chrome then restart all, it makes me lose a lot of time.
In fact, when I kill rails s and I launch lsof -wni tcp:3000
I still get chrome as:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
chrome 2112 leon 250u IPv6 84701 0t0 TCP [::1]:59116->[::1]:3000 (CLOSE_WAIT)
chrome 2112 leon 275u IPv6 80767 0t0 TCP [::1]:59080->[::1]:3000 (CLOSE_WAIT)
