System.Threading.ThreadAbortException:线程被终止-哪个线程

本文关键字：线程 终止 ThreadAbortException System Threading | 更新日期: 2023-09-27 18:19:20

我有一个网站，它不断地从另一个网站读取数据，并在地图上绘制信息。我有一个套接字以

开头
client.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0,
                    new AsyncCallback(ReceiveCallback), state);

ReceiveCallback读取数据并将其转储到Queue中供另一个线程分析，然后设置等待句柄以启动该线程。

readBytesWaitHandle.Set();

我很少得到以下错误

System.Threading.ThreadAbortException: Thread was being aborted.
   at System.Threading.WaitHandle.WaitOneNative(SafeHandle waitableSafeHandle, UInt32      millisecondsTimeout, Boolean hasThreadAffinity, Boolean exitContext)
   at System.Threading.WaitHandle.InternalWaitOne(SafeHandle waitableSafeHandle, Int64 millisecondsTimeout, Boolean hasThreadAffinity, Boolean exitContext)
   at System.Threading.WaitHandle.WaitOne(TimeSpan timeout, Boolean exitContext)
   at WebAPRS.PacketListener.readBytesBuffer() in c:'Users'Alan'Documents'Visual Studio 2013'Projects'WebAPRS'WebAPRS'PacketListener.cs:line 274

问题是-哪个线程正在中止?是运行ReceiveCallback的那个，还是等待的那个ReceiveCallback设置等待句柄

感谢艾伦

以下是ReceiveCallback 的代码
// run by the client thread (which is implicitly created)
    private void ReceiveCallback(IAsyncResult ar)
    {
        try
        {
            if (restarting) return;
            // Retrieve the state object and the client socket 
            // from the asynchronous state object.
            timeSpanSinceLastBytes = DateTime.Now - timeSinceLastBytes;
            timeSinceLastBytes = DateTime.Now;
            var state = (StateObject)ar.AsyncState;
            if (!state.workSocket.Connected)
            {
                reStartClient("Error: state.workSocket.Connected =false - Restarting");
                return;
            }
            var client = state.workSocket;
            // Read data from the remote device.
            var bytesRead = client.EndReceive(ar);
            if (bytesRead == 0)
            {
                reStartClient("ERROR: bytes==0 - Restarting");
                return;
            }
            // quickly store the buffer
            storeBytes buff = new storeBytes(state.buffer, bytesRead);
            byteQueue.Enqueue(buff);
            string data = Encoding.ASCII.GetString(state.buffer, 0, bytesRead);
            client.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0,
            new AsyncCallback(ReceiveCallback), state);
            // setoff the readBytes Thread
            readBytesWaitHandle.Set();
        }
        catch(Exception e)
        {
            reStartClient("ReceiveCallback failed : " + e.ToString());
        }
    }

你会看到我已经尽力抓住每一个我能想到的可能性。它经常在读取零字节时失败，然后重新启动。(我检查看到重启过程开始时没有进行)

catch块未捕获此错误。我的网站刚刚死亡(也许每12小时一次)，所以我有另一个线程运行检查每隔30秒读取一次ReceiveCallback输出的线程的运行状况，并打印出上面的错误消息。代码是:

private void checkRunning(object state)
    {
        if(! ((packetListener.readBytes.ThreadState == ThreadState.Running)||(packetListener.readBytes.ThreadState == ThreadState.WaitSleepJoin)))
        {
            packetListener.appendToDebugFile("readBytes thread not running "+packetListener.readBytes.ThreadState.ToString());
        }
        if(! ((packetListener.readStrings.ThreadState == ThreadState.Running) || (packetListener.readStrings.ThreadState == ThreadState.WaitSleepJoin)))
        {
            packetListener.appendToDebugFile("readStrings thread not running " + packetListener.readStrings.ThreadState.ToString());
        }
        if (packetListener.timeSpanSinceLastBytes > TimeSpan.FromSeconds(30))
        {
            packetListener.appendToDebugFile("bytes not seen for " + packetListener.timeSpanSinceLastBytes.ToString());
        }
        packetListener.appendToDebugFile("Threads running OK");
    }

System.Threading.ThreadAbortException:线程被终止-哪个线程

您超时了。增加ExecutionTimeout，因为它适用于我和其他人使用AsyncCallback并收到您发布的这个非常错误。

<compilation debug="false"></compilation>
<httpRuntime executionTimeout="1800"/> //1800 seconds - 30 minutes.

下面是在哪里进行上述更改的演练，下面是与您的情况类似的解决方案。
