由于系统缓冲区空间不足或队列已满，不能执行套接字上的操作。

异常详细信息: System.Net.Sockets.SocketException: 由于系统缓冲区空间不足或队列已满，不能执行套接字上的操作。

初步估计是这个方法出了问题。。。。（本机没问题，放到服务器就出现这个问题了）

/// <summary>
        /// 邮箱验证
        /// </summary>
        private void CheckUser()
        {
            string code = Request.QueryString["key"].Trim();
            string uid = Lang.Decrypt(code);

            sql = "select * from Sy_Authcode where UserID='" + uid + "' and Code ='" + Request.QueryString["key"].Trim() + "'";
            DataTable dt = SelectEntity.BaseAccess.GetDataTable(sql);
            if (dt.Rows.Count < 1)
            {
                Lang.ShowMessage("验证失败!");
            }
            else
            {

                if (SelectEntity.BaseAccess.GetDataTable("select * from HY_PageSet where userid='" + uid + "'").Rows.Count < 1)
                {
                    MemberCompetence.SetDefaultPageSet(uid);
                    CreatHTML.CreatePage(uid, MemberCompetence.IsJianCaiUser(uid).Trim() != "jc" ? true : false);
                }
                sql = "update Sy_Authcode set IsChecked = 1 where UserID='" + uid + "' and Code ='" + code + "'";
                SelectEntity.BaseAccess.Update(sql);
                Lang.ShowMessage("验证成功，您现在可以登陆后台进行操作了!");
            }
        }

这个方法要改？
还是做什么措施？
看了网上的一些回答好像不怎么适合我这个 。。。。。。。

分不够可以+

系统中毒
数据传输就及时接收到缓冲区
清除资源
还有其他程序程序导致
