Hi Louis ! Yes, I have the same understanding of the problem ! So if the fix is available, and you do port it, I guess you can close the ticket :) Thanks a lot for you work and effort ! Br, Peter.

So to clarify you need to have this in your haproxy.cfg: """ ... global maxconn 32000 ulimit-n 65536 user haproxy group haproxy nbproc 2 ... """ the problem is more visible if you set the nbproc to higher number. service haproxy stop --> will only stop on of the haproxy processes. The problem is so that start-stop-daemon can't handle pid files with multiple lines. Only stopping the first one. HAProxy does write all the pids started by itself into the pid file, so the problem is not in HAProxy, but in the start-stop-daemon or more likely in the init scrip of haproxy. One solution or workaround is to remove pidfile option of start-stop-daemon in the init script, than it wil work as killall and will stop the haproxy processes properly. To proof you can try this sequence: service haproxy start #if its not running ps ax | grep haproxy | grep -v grep | wc -l #this should report 2 service haproxy restart ps ax | grep haproxy | grep -v grep | wc -l #this will report 3 The workaround as a diff: root@ubi1:/opt# diff /etc/init.d/haproxy /etc/init.d/haproxy.orig 62c62 < --retry 5 --exec $HAPROXY || ret=$? --- > --retry 5 --pidfile $PIDFILE --exec $HAPROXY || ret=$? extra infos: root@ubi1:/opt# lsb_release -rd Description: Ubuntu 14.04.3 LTS Release: 14.04 root@ubi1:/opt# apt-cache policy haproxy haproxy: Installed: 1.4.24-2ubuntu0.2 Candidate: 1.4.24-2ubuntu0.2 Version table: 1.5.3-1~ubuntu14.04.1 0 100 http://us.archive.ubuntu.com/ubuntu/ trusty-backports/main amd64 Packages *** 1.4.24-2ubuntu0.2 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 Packages 100 /var/lib/dpkg/status 1.4.24-2 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/haproxy/+bug/1481737/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-ha Post to : ubuntu-ha@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-ha More help : https://help.launchpad.net/ListHelp
