由于代码已经过优化或者本机框架位于调用堆栈之上，无法计算表达式的值

Question

我的日志记录模块总是抛“由于代码已经过优化或者本机框架位于调用堆栈之上，无法计算表达式的值”异常，而且此异常一出就把我的线程给停了，也无法捕获，求高手指教。附代码：
//创建后台线程往数据库里写日志
private static void Initialize()
        {
            LogStop = false;
            interva = tempInterva;
            sendThreadNum = Convert.ToInt16(System.Configuration.ConfigurationManager.AppSettings["DBLSendThreadNumber"].ToString());
            tempInterva = Convert.ToInt16(System.Configuration.ConfigurationManager.AppSettings["DBLSendInterval"].ToString());
            batchSend = Convert.ToInt16(System.Configuration.ConfigurationManager.AppSettings["DBLBatchSend"].ToString());
            sendSleepTime = Convert.ToInt16(System.Configuration.ConfigurationManager.AppSettings["DBLSendSleepTime"].ToString());            if (LogQueue == null)
            {
                lock (CreateLock)
                {
                    if (LogQueue == null)
                    {
                        LogQueue = new QueueList();
                        for (int i = 1; i <= sendThreadNum; i++)
                        {
                            //创建后台线程，不停的将数据信息写入数据库
                            System.Threading.Thread thread = new System.Threading.Thread(new System.Threading.ThreadStart(WriteLogInto));
                            thread.IsBackground = true;
                            thread.Start();
                            System.Threading.Thread.Sleep(interva + i);
                            ThreadHash.Add("DBLog后台处理线程", thread);
                        }
                    }
                }
            }
        }//将日志信息放入队列交给写日志进程处理
private static void WriteLogInto()
        {
            while (!LogStop)
            {
                try
                {

                    //GC.WaitForPendingFinalizers();
                    SendLogEntityByQueue();
                    System.Threading.Thread.Sleep(interva);                }
                catch//在此会捕获到标题中的异常，而且主线程在异常出现后不久就停止了，不知道为什么，而且每次捕获到异常的地方也不一样
                {
                    XException xe = FuncLib.BuildXExcpetion("DBLog Happen A Exception", null);
                    LogRecordWrap.Send(xe.ToString(), PEConsts.LOG_EXCEPTION);
                }
            }
        }//分批写日志

                        if (interva < 3000)

Answer 1

catch（Exception e）//在此会捕获到标题中的异常，而且主线程在异常出现后不久就停止了，不知道为什么，而且每次捕获到异常的地方也不一样
  {
    throw; //什么也不干
   // XException xe = FuncLib.BuildXExcpetion("DBLog Happen A Exception", null);
   //LogRecordWrap.Send(xe.ToString(), PEConsts.LOG_EXCEPTION);
  }
  }

Answer 2

没用，只要DbHelperSQL.ExecuteSql(sb.ToString(), paras);一出异常主线程过会儿就会停了，有时候都走不到那儿去。

Answer 3

楼主你用到的LogQueue变量是线程安全的吗？
DbHelperSQL有关闭数据库操作吗？
