server 端出现疯狂 EOF错误

[oikomi]

hi
使用json协议的服务端如下

func (s *GateWayServer) serverSessionLoop(session *libnet.Session) {
logrus.Infof("[gateway] new session coming in, id is %d", session.ID())
for {
logrus.Info("start receive")
req, err := session.Receive()
common.CheckErr(err)

	logrus.Infof("req msg is %v", req)
	logrus.Infof("req type is %v", reflect.TypeOf(req))
	s.parseReq(req, session)
	common.CheckErrWithMsg(err, "parse failed")
}

}

客户端发送结束关闭连接，但是服务端大量出现这种EOF错误，没找到原因，大佬帮忙看看
