HTTP连接停留在close_wait状态

Question

I'm using gin to build a simple api server. right now, after the server started a few minutes later, all of incoming requests were stuck. After checking connections state , I got a message like below :

I already have tried to set c.Request.Close=true or c.Header("Connection","close") or both of them, but it was not working. I was wondering if anyone can help me fix this issue.

UPDATE-1 the way to start server

            runtime.GOMAXPROCS(runtime.NumCPU())
            //start serving
            r := gin.New()
            r.Use(gin.LoggerWithWriter(logFile))
            r.Use(gin.RecoveryWithWriter(logFile))
            r.Use(handler.SetResponseHeader())
            controller.Router.RegisterRouter(r, cfg)

            //r.Run(cfg.SvcHost)
            s := &http.Server{
                Addr:    cfg.SvcHost,
                Handler: r,
            }
            s.ListenAndServe()

UPDATE-2

after temporarily disabling the global gorm.DB instance and creating a new db connection for each request, this issue didn't occur any more.

TCP is waiting for you to close those connections. Probably you have read end of stream from them and have ignored it.
