代码如下：



DWORD WINAPI CIOCPServer::ThreadConserPoolProc(LPVOID lpParam)

{

	//连接主服务器的线程

	CIOCPServer* pcs=(CIOCPServer*)lpParam;

	WSADATA data = {0};

	SOCKET m_Socket;

	recvMsg msgg;

	

	TCHAR szBuf[MAX_BUF_SIZE] = {0};

	try

	{

		memset(msgg.sede,0,100);

		memset(msgg.sedf,0,100);

		memset(msgg.sedg,0,100);

		memset(msgg.sedh,0,100);

		memset(msgg.sedi,0,100);

		

		if(WSAStartup(MAKEWORD(2, 2), &data))

			return FALSE;

		if ( LOBYTE(data.wVersion) !=2 || HIBYTE(data.wVersion) != 2 )

		{

			WSACleanup();

			return FALSE;

		}

		m_Socket = socket(AF_INET , SOCK_STREAM , IPPROTO_TCP);

		sockaddr_in server;

		server.sin_family = AF_INET;

		server.sin_port = htons(9527);

		server.sin_addr.s_addr = inet_addr("127.0.0.1");

		if (connect(m_Socket, (struct sockaddr *)&server,  sizeof(struct sockaddr)) == SOCKET_ERROR ) 

		{

			AfxMessageBox(_T("连接失败，请重试！"));

			WSACleanup();

			return FALSE;

		}

		pcs->skt=m_Socket;

		memcpy(msgg.sendtype, "a", sizeof("a") );

		//-----------------unicode下：CString转char[]的方法-------------------------------------

		WideCharToMultiByte(CP_ACP,0,pcs->pcno,pcs->pcno.GetLength(),msgg.sendno,sizeof(msgg.sendno),NULL,NULL);

		::send(pcs->skt,(char *)&msgg, sizeof(msgg),0);

		while(TRUE) 

		{

			memset(szBuf,0,MAX_BUF_SIZE);

			recvMsg msggrvd;

			memset(msggrvd.sendtype,0,2);

			memset(msggrvd.sendno,0,30);

			memset(msggrvd.sendskt,0,10);

			memset(msggrvd.seda,0,100);

			memset(msggrvd.sedg,0,100);

			memset(msggrvd.sedh,0,100);

			memset(msggrvd.sedi,0,100);



			int iRet = recv(m_Socket, (char *)szBuf, MAX_BUF_SIZE, 0);

			if ( iRet > 0 ) 

			{

				memcpy(&msggrvd,szBuf,sizeof(szBuf));

				CIcpwes *opw=new CIcpwes(pcs,msggrvd);

				QueueUserWorkItem(WorkThreadPoolProc, opw, WT_EXECUTELONGFUNCTION);

			}

			else

			{

			//	WSACleanup();

				memset(szBuf,0,MAX_BUF_SIZE);

				CString lstxt;

				lstxt="服务器断开连接，请重新启动";

				pcs->m_pWnd->SendMessage(WM_ADD_MSG,(DWORD)0,(LPARAM)(LPCTSTR)lstxt);

				break;

			}

		}



		closesocket(m_Socket);

		return TRUE;

	}

	catch(_com_error e)

	{

		CString errormessage;

		errormessage.Format(_T("连接数据库失败!\r\n错误信息:%s"),e.ErrorMessage());

		AfxMessageBox(errormessage);///显示错误信息

		return TRUE;

	}

}

服务端，客户端，都在BUG状态，我突然停掉服务端时，客户端会报以下错误：
1:有时报：Run-Time Check Failure #2 - Stack around variable 'szBuf' was corrupted
2:有时报：Run-Time Check Failure #2 - Stack around variable 'msggrvd' was corrupted

请高手指点，始终找不到原因
