zhangwei17 opened a new issue #862: 使用ip:port字符串的channel出现地址混乱的情况
URL: https://github.com/apache/incubator-brpc/issues/862
 
 
   **Describe the bug (描述bug)**
   当前我的一个服务即属于服务端，也属于客户端，有需要请求的下游。服务端监听的端口为33001，请求的下游的端口为33002，是在栈上使用channel。当服务压力较大的时候会出现地址混乱无法连接下游的情况：在日志中会打印类似如下信息的日志
   ```
   2019-07-30T10:02:54,471.421 ERROR xxxx Fail to send thrift request, [E110]Fail to connect Socket{id=326417633629 addr=10.132.93.80:33002:33001} (0x0x183ce9a00): Connection timed out [R1][E112]Not connected to 10.132.93.80:33002 yet, server_id=197568615140 [R2][E112]Not connected to 10.132.93.80:33002 yet, server_id=197568615140 - xxxx.cpp:76#void xx::xxxxxxx::OnRPCDone<T>::Run() [with T = xx::BrpcXxxRequest] - 18164@xxxx.xxx.xx.xxx
   ```
   
   请求下游地方的代码大致如下：
   ```
     brpc::Channel channel;                                                                                                                                                                      
     brpc::ChannelOptions options;
     options.protocol = brpc::PROTOCOL_THRIFT;
     options.connection_type = "pooled";
     options.timeout_ms = 1000;
     options.max_retry = 1;
     //这里的node_data是传入函数的形式为ip:port的下游主机串。
     //由于选择机器是预先做的工作，这里就用的ip:port参数的channel初始化，channel也就在栈上使用了
     if (channel.Init(node_data.c_str(), "", &options) != 0) {
       XLOG_ERROR("Fail to initialize channel");
       return 0;  
     }   
   
     brpc::ThriftStub stub(&channel);
     Response req;
     req.__set_data(data);
   
     OnRPCDone<Response> *done = new OnRPCDone<Response>();
   
     stub.CallMethod<Request, Response>((const char*)"SendBatchCandidates", &done->cntl, &resp, &done->resp, done);
   
   ```
   
   有怀疑过传入的node_data是否有问题，但是打印相关日志并未发现异常。所以想知道官方有没有碰到过这样的case，或者有没有思路可以考虑一下。
