錯誤 10055: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full
window下通過cmd命令 netstat -ano，查看到nginx端口出現大量TIME_WAIT
通過動態端口範圍解決：
netsh int ipv4 shoynamicport tcp查看當前配置
通過命令修改端口數
netsh int ipv4 set dynamicport tcp start=20000 num=25000
