单位上一个用于通讯的服务器上的程序出了问题: 服务器程序使用UDP服务端,用的是异步Socket模式,服务器刚搭建好的时候没什么问题,最近由于通讯客户端增多(da大概1500个左右)后,出现这样的问题: mySocket.Bind(ipe);    mySocket.BeginReceiveFrom(obj.buffer,0,UdpTranslateObj.BUFFER_SIZE,SocketFlags.None,     ref obj.endPoint,new AsyncCallback(ReceiveCallBack),obj); private void ReceiveCallBack(IAsyncResult ar)  {   UdpTranslateObj obj = (UdpTranslateObj)ar.AsyncState;   try   {    int k = obj.udpSock.EndReceiveFrom(ar,ref obj.endPoint);    if(k > 0)    {     ReceiveEventArgs e = new ReceiveEventArgs();     e._ReceiveBytes = new byte[k];     Array.Copy(obj.buffer,0,e._ReceiveBytes,0,k);     e._RemoteEndPoint = obj.endPoint;     OnReceive(e);    }   }   catch(SocketException oe)   {    if(oe.ErrorCode == 10054 )    {     if(this.ActiveSymbol)     {      try      {       obj.udpSock.BeginReceiveFrom(obj.buffer,0,UdpTranslateObj.BUFFER_SIZE,SocketFlags.None,        ref obj.endPoint,new AsyncCallback(ReceiveCallBack),obj);      }      catch       (Exception oee)      {       this.mySocket.Close();       this.mySocket = null;       System.Threading.Thread.Sleep(500);       Start();       return;       }     }    }   }   catch(Exception oe)   {   WriteErrLog("UDP接收错误:" + oe.ToString());       }   if(this.ActiveSymbol)   {    try    {     obj.udpSock.BeginReceiveFrom(obj.buffer,0,UdpTranslateObj.BUFFER_SIZE,SocketFlags.None,      ref obj.endPoint,new AsyncCallback(ReceiveCallBack),obj);    }    catch     (Exception oe)    {     this.mySocket.Close();     this.mySocket = null;     System.Threading.Thread.Sleep(500);      }   }     } 问题:程序启动时没问题,大概运行2~3小时后出现这个问题 使用sock.BeginReceiveFrom后未执行回调函数ReceiveCallBack 不知道怎么回事?   2007-10-22: 怀疑一:程序中其它地方投递的异步操作太多,以至于windows操作系统线程池被占满而得不到执行?  此怀疑尚未证实..
