netstat TCP connection under time_wait state: 1. This is a state that is in the state before the connection is completely closed;2. You usually have to wait 4 minutes (Windows Server) for the time to shut down completely;3. TCP connections in this state consume resources such as handles and ports, and the server consumes resources to maintain these connection states; 4. Resolving this time_wait TCP connection only allows the server to quickly recl
