Subject: PROBLEM: Infinite listens for haproxy in /proc/net/tcp

This happens whether the file is read directly, or using netstat.
It looks like haproxy has millions of LISTEN.

We've tried to see if there is a definitive count, but after 20 minutes of 
running cat /proc/net/tcp we gave up. This is an intermittent problem.

According to ss, there is about 5500 connections running on the system.

ss -t -l -p outputs the correct information.
