As a reminder (to me), I sent a patch in december (just before the 1.7.0 release), which immediately closes the HTTP keep-alived connections. Currently, during the soft stop, HTTP connections are only closed when a request is processed, it doesn't do anything on connections already in an idle state. I didn't spend more time on it but having a quick look at it, it may be ready to merge soon. About TCP connections, while I wrote the patch, I was thinking about a global "grace timeout", which will enforce haproxy exit if the soft stop takes too long (for example when tcp connections don't expire). Something like : global grace 30s Would it be something acceptable Willy ? Cheers, Cyril Bonté
