Cannot use rosserial_server [closed]

edit

Hi,

I want to use rosserial_server for high speed communication.

But, I use rosserial_server serial_node.cpp

$ rosrun rosserial _server serial_node

I get the error message

[INFO] [1531356226.107258127] Opened /dev/ttyACM0

[WARN] [1531356226.117567124] Socket asio error, closing socket: asio.misc:2

[WARN] [1531356228.119077841] Socket asio error, closing socket: asio.misc:2

 ...

So,What do I do to solve this error?

(I use Ubuntu16.04LTS,kinetic,ros_lib_kinetic)
