端口转发程序出错，请懂的人指点一下。

[annhf]

以下源码是端口转发程序，数据转发的源码，在转发时小数据不会出现问题，但是在大数据时程序程序会出错，显示错误信息为WARN:Close socket.不知道为什么，请各位大虾指点。如果分数不够可以增加。

DWORD WINAPI TranslateData(LPVOID pvParam)
{
STACK<SOCKS> *SocketData = (STACK<SOCKS>*)pvParam;
SOCKS AccAndMapSocket = SocketData->Pop();
WSAEVENT hEvents[2];
hEvents[0] = WSACreateEvent();
hEvents[1] = WSACreateEvent();
if (WSAEventSelect(AccAndMapSocket.AccSocket, hEvents[0], FD_READ | FD_CLOSE))
{
printf("ERROR:WSAEventSelect 1 error.\r\n");
goto error;
}
if (WSAEventSelect(AccAndMapSocket.MapSocket, hEvents[1], FD_READ | FD_CLOSE))
{
printf("ERROR:WSAEventSelect 2 error.\r\n");
goto error;
}
while (1)
{
