This is haproxy 1.6.3-1ubuntu0.2 on Xenial/16.04 running on amd64
hardware.
Reproduction steps:
1. Install haproxy and configure it to use a TLS certificate
2. Renew and replace that certificate
3. Run 'service haproxy reload'
4. Sometimes this starts serving the new certificate, sometimes it doesn't

Title:
service haproxy reload sometimes fails to pick up new TLS certificates
Status in haproxy package in Ubuntu:
New
Bug description:
I suspect this is the same thing reported on StackOverflow:
"I had this same issue where even after reloading the config, haproxy
would randomly serve old certs. After looking around for many days the
issue was that "reload" operation created a new process without
killing the old one. Confirm this by "ps aux | grep haproxy"."
https://stackoverflow.com/questions/46040504/haproxy-wont-recognize-
new-certificate
In our setup, we automate Let's Encrypt certificate renewals, and a
fresh certificate will trigger a reload of the service. But
occasionally this reload doesn't seem to do anything.
Will update with details next time it happens, and hopefully confirm
the multiple process theory.
