I actually had/have an issue with the systemd-wrapper haproxy uses in 1.7 where systemd gets confused when doing a reload + a restart before all sessions are closed. This caused haproxy to completely stop accepting connections until the systemd timeout kicked in and sent a kill -9

I reported it and was told it might not affect 1.8 since the systemd-wrapper is removed there, so gonna give this a try soon. See this thread: https://www.mail-archive.com/[email protected]/msg27404.h...

(And I switched to only doing a reload notify in Ansible together with the hard-stop-after option in haproxy which is OK for me as well in 1.7)
