/tmp/php-cgi-71.sock

2021/03/11 13:51:06 [error] 2209#0: *1251111 connect() to unix:/tmp/php-cgi-71.sock failed (11: Resource temporarily unavailable) while connecting to upstream, client: 110.24.15.5, server: app.xxx.cn, request: "GET /api/order/getAuth?uuid=fexasdq&verify=MDAwMDAwMDAwMMbarGHJZ4uxmImynrCfumay372wsH5gcg&ver=3.0.0.202103090 HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-cgi-71.sock:", host: "app.baidu:17008"

正常时候不会有这个报错，请求量每秒50000~60000左右就会报错，还有加负载均衡会报错
