Unable to terminate the program by sending a TERM signal to the main process

[bourne-3]

Update:

func (t *St) SH() {

	.... (some code)

	c := make(chan os.Signal, len(sigs))
	signal.Notify(c, sigs...)

	for {
		select {
		case sig := <-c:
			t.handle(sig)
		case <-t.ch:
			return
		}
	}
}

I found this function above in the code
When I commented out this function, it closed properly
... Why this happen..?

Also, I did an experiment and without any wrapping, with the default gin framework, when I call

kill -SIGUSR2 ${master_pid}

I get an error as follows

accept tcp [::]:5001: use of closed network connection

Is this error normal and do I need to deal with it?

======
Does this error report have the same effect as the http.ErrServerClosed ?

// ErrServerClosed is returned by the Server's Serve, ServeTLS, ListenAndServe,
// and ListenAndServeTLS methods after a call to Shutdown or Close.
var ErrServerClosed = errors.New("http: Server closed")
