标题: 很急！！请教大侠，和第三方socket通讯出现FIN_WAIT_2，如何解决？
我方程序如下：
{
      /*
      ** read the left of the transaction from the socket
      */
      if( iLeft > MAX_DATA_LEN )
         iRead = MAX_DATA_LEN;
      else
         iRead = iLeft;

      iLen = u_read( commid, pczTmpBuf, iRead );
      if( iLen <= 0 )
      {
         alarm( 0 );
         return ( -1113 );
      }

      /*
      ** add the string ever time
      */
      memcpy( ptr, pczTmpBuf, iLen );
      iLeft = iLeft - iLen;
      ptr = ptr + iLen;
   }
   while( iLeft > 0 ); /* all has recevied */

   fcntl ( commid ,F_SETFL ,O_NONBLOCK ) ;
      shutdown ( commid , 2 ) ;
      CloseSocket ( commid ) ;

我方检测端口状态如下：

通讯完成后直接close行吗？

两边的连接close的不一致导致
