客户端请求流量高后请求server端报[E110]Fail to connect Socket错误

客户端请求服务端的连接超时时间已改到1秒，还是存在大量的E110错误，错误率基本到达100%，然后触发熔断。
更新了最新的brpc版本还是存在这个问题

Start by reproducing the reported E110 socket failures under high client request traffic using the connection timeout and current brpc version described in the issue. Trace the client-to-server connection path and record the conditions that trigger the error and circuit breaker. Done means the cause is identified and a verified fix or a precise reproduction is documented.
