The problem: when I reload haproxy, my backend server goes DOWN each time because of DNS timeout, and the output logging is: [WARNING] 014/190450 (22) : Reexecuting Master process [WARNING] 014/191701 (22) : parsing [/usr/local/etc/haproxy/haproxy.cfg:51]: 'log-format' overrides previous 'option h…

Can you try without nbthread please?

Yeah, it works fine when i set nbthread to one. But we hope to enable the multi-thread feature, please does a fix in the next release. Looking forward to it and thanks a lot.

Absolutely, it’s just to confirm whether this is related to multithreading or not. Can you confirm that you had multithreading enabled when using 1.8.2 or so multithreading did actually work together with DNS resolution in 1.8.2?

@lukastribus , I’ve found one more problem. Some processes stop to discover and add new backend servers. There is no any errors or warnings in the log file grep nbp /etc/haproxy/haproxy.cfg nbproc 6 for i in $(seq 1 6); do echo “show servers state” | socat unix-connect:/var/run/haproxy-$i.sock…

Here is the same server after 24hours for i in $(seq 1 6); do echo “show servers state” | socat unix-connect:/var/run/haproxy-$i.sock stdio|grep ec2.int|wc -l; done 37 37 37 37 29 37 little bit later: for i in $(seq 1 6); do echo “show servers state” | socat unix-connect:/var/run/haproxy…

@ASA please don’t hijack other threads. If you have a new issue kindly open a new thread. Also provide the configuration and the output of haproxy -vv (not -v).
