APISIX backlog is currently the default value(Usually 128), and it is prone to packet loss in the listen queue and semi-link queue in large concurrent scenarios.
APISIX is based on nginx. The backlog value of nginx is determined by two system configurations and one configuration value in nginx.conf: 1. System parameters: sysctl net.ipv4.tcp_max_syn_backlog sysctl net.core.somaxconn 2. nginx.conf: default_server backlog How to check the backlog size of APISIX process? Use the 'ss -lnt' command
