Re: haproxy keeps sending traffic to an offine backend
thanks Willy, I'll test this changing this option. If it keep sending traffic to offline hosts, how can I work around/fix this? It will be some code to fix or something that I can't workaround?

haproxy keeps sending traffic to an offine backend
Hi, I didn't found and answer for this so I'm trying this mailing list. I'm using haproxy on freebsd and I'm getting a very strange behavior when a backend is offline I can see it offline on haproxy stats but connections keep being forwarded to offline member and failing to the client(checked with tcpdump). When I remove the offline member, I get a normal status again. tested on many 1.4.x version, including latest 1.4.20 Thanks for any help att, Marcello Coutinho
