1053 windows服务没有及时响应

Question

I have one Web app running in IIS and communicates to a Windows Service through WCF hosted in the same machine. Internally Windows Service executes various job and sometimes it is quite busy with processing User requests. At 1st I had the issue with Start of Service because it some imes take much time to Start & eventually throws the Error ie Service Timeout. To fix this I moved the code to another Thread instead of the Main Thread. Everything works fine but now I observed that some times I am getting the error on Service Stop ie

**1053 windows service did not respond in timely fashion**

My Service OnStop() code:

protected override void OnStop()
        {
            // Stop the WCF service
            if (myServiceHost != null)
            {
                myServiceHost.Close();
                myServiceHost = null;
            }

            // Stop the scheduler

            if (myScheduleManager != null)
            {
                myScheduleManager.Stop();
            }

            // Update the registry value
            Logger.GetInstance().LogEvent(this.GetType().Name, LogLevel.INFO, "Updating registry...");
            Settings.GetInstance().LastStopTime = DateTime.Now.ToString();

            Logger.GetInstance().LogEvent(this.GetType().Name, LogLevel.INFO, "Service stopped.");
        }

It generally happens when Service is too busy. But finally it stops after 30-40 mins of time. I know this happens due to Time out issue in Windows Service coz the default time is very less & it treats it as Time out.

My question what is the best practice to avoid such bottle necks means shall I move my Stop related tasks under another Thread & do asynchronous call to release resources in that Thread. But what will happen if during release resources, User will Start the Service?

Answer 1

Just guessing, but perhaps it will help to track down the problem:

You have this myScheduleManager.Stop() which, (i guess) waits for processes to be finished. This is nice, but Windows only gives you 30 Seconds to execute ServiceBase.OnStop() .

If you are doing asynchronous processing here, you could perhaps implement the CancellationPattern by using the CancellationTokens from the .NET-Framework.

Answer 2

The easy approach probably you can identify to build a boolean type IsRunning in your myScheduleManager and determine during the OnStop()

if (myScheduleManager.IsRunning)
    myScheduleManager.Stop();

however, you have different threads finishing the processes which could over 30 seconds but you also can do abort your processes by applying

if (myScheduleManager.IsRunning && !_workerThread.Join(TimeSpan.FromSeconds(30))
    _workerThread.Abort 

myScheduleManager.Stop();

However, I didn't see the full code snippets so that's my guess to your scenario.

只是猜测但它可能有所帮助：确保将解决方案配置设置为Release而不是Debug。
