We use /usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -D -p /var/run/haproxy.pid -sf <pid>
In production to gracefully restart haproxy. But sometimes we notice that the old haproxy process taking a long time to go away and if we make multiple updates and it would result in multiple haproxy processes for a long time. How can we make sure the old haproxy can go away in a reasonable amount of time?
