Hi Yalei, Thanks for checking!
@YeXin, does this [1] fix your issue? Note that the test server implementation is not the most robust nor the most tested. I actually often test the reverse of what you did, i.e., builtin server with tcp_echo client. The tcp_echo client is somewhat better than the server as it can do more than 1 connection, albeit limited to the number of physical threads available.
