Hello, I've finally updated our load balancer, using HAProxy 2.0, to HAProxy 2.4 \o/ I was motivated by both the EOL on 2.0, and by a recurring segfault everytime we reloaded. btw, that segfault is now gone with 2.4 :)
I did not update to a newer version because we are still heavy users of "nbproc" that we still need to convert to thread usage (and replace bind-process by 'process'). For those interested, the (small) necessary config changes were : - option httpchk syntax (use http-check) - some healthchecks not working anymore on servers with "send-proxy-v2-ssl-cn ssl-check", due to an unresolved bug in Apache 2.4 ( https://bz.apache.org/bugzilla/show_bug.cgi?id=63893). Everything seems to run smoothly, but on the monitoring, the number of active sessions (scur) dropped significantly (only one third active sessions compared to before), even after several hours. I did not make any change on keep alive or timeouts, that's why I'm wondering if any modifications between 2.0 and 2.4 may explain this behaviour. Cheers, Olivier
