Running Haproxy 1.9.4 on Ubuntu 14.04, and use an init.d script to manage the process and auto-start at system boot. The auto-start part works fine.

For some reason, system haproxy restart and system haproxy stop do not affect the process at all as the process just keeps running. I attach the init.d script as below

#!/bin/sh

### BEGIN INIT INFO

# Provides:          haproxy

# Required-Start:    $local_fs $network

# Required-Stop:     $local_fs

# Default-Start:     2 3 4 5

# Default-Stop:      0 1 6

# Short-Description: fast and reliable load balancing reverse proxy

# Description:       This file should be used to start and stop haproxy.

Even more strangely, can't even kill off the process by sending SIGTERM or SIGSTOP in htop. Any idea why?
