Socket通信死循环有关问题~大家帮忙分析~有源码

Socket通信死循环问题~大家帮忙分析~有源码
奇怪，在执行下面代码的时候，我开了个客户端每10毫秒发送一次数据，服务端就接收一个数据，但运行大约20几个小时以后，即使我关掉发送数据的客户端，服务器端依然能够接收到数据，一直在死循环，奇怪了晕，大家帮忙分析分析原因，感激不尽~~

C# code

private void BeginReceive()        {            try            {                StateObject so = new StateObject(this.mSocket);                mSocket.BeginReceive(so.Buffer, Session.OFFSET, so.Buffer.Length, SocketFlags.None, this.ReceiveCallBack, so);            }            catch (Exception ex)            {                TriggerErrorEvent(ex);            }        }        private void ReceiveCallBack(IAsyncResult result)        {            try            {                StateObject so = (StateObject)result.AsyncState;                int dataLength = so.Socket.EndReceive(result);                Logger.Debug(string.Format("Read Message Successed, SessionID:{0} Count {1}", this.SessionID, this.mReadCount++));                so.Socket.BeginReceive(so.Buffer, Session.OFFSET, so.Buffer.Length, SocketFlags.None, this.ReceiveCallBack, so);            }            catch (Exception ex)            {                TriggerErrorEvent(ex);            }        }

C# code

 private void ReceiveCallBack(IAsyncResult result)        {            try            {                StateObject so = (StateObject)result.AsyncState;                int dataLength = so.Socket.EndReceive(result);                if (dataLength > 0)                {                    Logger.Debug(string.Format("Read Message Successed, SessionID:{0} Count {1}", this.SessionID, this.mReadCount++));                    so.Socket.BeginReceive(so.Buffer, Session.OFFSET, so.Buffer.Length, SocketFlags.None, this.ReceiveCallBack, so);                }            }            catch (Exception ex)            {                TriggerErrorEvent(ex);            }        }
