Multiple threads create non-blocking sockets to simulate heavy network load. Most sockets work well, but occasionally some sockets can send data via non-existent local port, and can read data from the port as well. Maybe I am not acquainted enough with epoll networking programming, and even not sure if it is a bug in no-blocking i/o or epoll, and also not certain which websites are the right place to discuss epoll or no-blocking i/o technologies. Anyone has any ideas would be greatly appreciated.
