vaavaav opened a new issue, #2816: URL: https://github.com/apache/brpc/issues/2816
**Describe the bug (描述bug)** According to `channel.h`, setting `timeout_ms` to `-1` will make the `Channel` block on requests. However, this fails and shows the following error over and over again (even if no more requests are being made): `W1106 15:03:26.337735 3784702 4294969859 /.../brpc/src/brpc/socket.cpp:1361] Fail to wait EPOLLOUT of fd=3: Connection timed out `. However, this does not happen if the IP provided for the channel to connect is "localhost," more precisely, "127.0.0.1". **To Reproduce (复现方法)** For example, 1. Compile the `echo_c++` example provided by brpc (but comment out all logging instructions for easier reading). 2. Run it like so: `./echo_client --timeout_ms=-1 --server="128.0.0.1:50000"`. (I am aware that this IP is not for "localhost" but, again, this fails for IPs that are not "localhost"). **Expected behavior (期望行为)** The request should be blocked until an answer is received. An example of correct behavior is following the example above but run it like so: `./echo_client --timeout_ms=-1 --server="127.0.0.1:50000"`. **Versions (各种版本)** OS: 5.4.0-187-generic Compiler: gcc (Ubuntu 9.4.0-1ubuntu1~20.04.2) 9.4.0 brpc: 1.11.0 protobuf: 3.21.6.0 **Additional context/screenshots (更多上下文/截图)** Commented out portions of the `echo_c++` example:  -- This is an automated message from the Apache Git Service.
