Hello, I've configured the so_keepalive option for a server (this is also my default server). I do have other server configs listening to the same port. ======== listen 9822 default_server so_keepalive=on; listen 29822 ssl http2 default_server so_keepalive=on; ========
My sysctl settings are set to : ======== net.ipv4.tcp_keepalive_time = 120 net.ipv4.tcp_keepalive_probes = 10 net.ipv4.tcp_keepalive_intvl = 120 ======== However, I see that no tcp keepalive packets are being sent on outbound connections (from nginx to the upstream). I also checked the output of 'netstat -an --timers' I see that no outbound sockets have the 'keepalive' flag. All of them are 'off'. If it matters, the server config which actually servers this request is not the default one, but one of the other configs. I took a quick look at the code and the 'SO_KEEPALIVE' options only shows up on functions which deal with listening sockets. Does this mean that nginx does not honor this option for outbound connections?
