Windos下socket和QUdpSocket都有内存泄漏怎么回事啊？

[MAYBEALL]

通过socket或者QUdpSocket死循环往组播或单播地址发送数据，会有严重的内存泄漏，超过了我发送的数据量的2倍，不知道是怎么回事啊？

	QUdpSocket sock;
	QHostAddress addr("235.1.1.2");
	QByteArray data(8192,0);
	WSADATA wsaData; 
	int Ret = WSAStartup(WORD((1<<8)|1),&wsaData);
	SOCKET m_socket = socket(AF_INET, SOCK_DGRAM, 0);
	SOCKADDR_IN m_socketInfo;
	m_socketInfo.sin_family = AF_INET;
	m_socketInfo.sin_port = htons(18189);
	m_socketInfo.sin_addr.s_addr = inet_addr("235.1.1.2");
	int m_len = sizeof(SOCKADDR);
	SOCKADDR* m_to = (SOCKADDR*)&m_socketInfo;
	int _num = 0;
	while(1)
	{
		 //int sendSize = sendto(m_socket,data.data(),data.size(),0,m_to,m_len);
		 int sendSize = sock.writeDatagram(data.data(),data.size(),addr,8899);
		//qDebug()<<"sendSize:"<<sendSize;
 		Sleep(1);
	}

就这段代码，直接死循环，内存飙涨
