Topshelf halts service recovery after third attempt


I am using Topshelf to create a Windows Service. This service will attempt recovery the first 3 failures, but after that, it no longer work.

Inspecting the service in Services on the host reveals:

First Failure:          Restart the Service
Second Failure:         Restart the Service
Subsequent Failures:    Restart the Service
Reset fail count after: 1 days
Restart service after:  2 minutes

The service recovery code looks like this:

f.EnableServiceRecovery(r =>
{
    r.RestartService(2);
    r.RestartService(5);
    r.RestartService(5);
    r.OnCrashOnly();
    r.SetResetPeriod(1);
});

Inspecting the Event Log shows the following messages after failed recovery:

The MyService service terminated unexpectedly.  It has done this 1 time(s).  The following corrective action will be taken in 120000 milliseconds: Restart the service.
The MyService service terminated unexpectedly.  It has done this 2 time(s).  The following corrective action will be taken in 300000 milliseconds: Restart the service.
The MyService service terminated unexpectedly.  It has done this 3 time(s).  The following corrective action will be taken in 300000 milliseconds: Restart the service.
The MyService service terminated unexpectedly.  It has done this 4 time(s).

As is evident from the above. The fourth time does not trigger recovery.

Is this a Windows error, a Topshelf issue, or is there something wrong in my configuration?


Solution

  • You must set bottom config for topshelf recovery setting:

    x.EnableServiceRecovery(rc =>
                    {
                        // Has no corresponding setting in the Recovery dialogue.
                        // OnCrashOnly means the service will not restart if the application returns
                        // a non-zero exit code.  By convention, an exit code of zero means ‘success’.
                        rc.OnCrashOnly();
                        // Corresponds to ‘First failure: Restart the Service’
                        // Note: 0 minutes delay means restart immediately
                        rc.RestartService(delayInMinutes: 0); 
                        // Corresponds to ‘Second failure: Restart the Service’
                        // Note: TopShelf will configure a 1 minute delay before this restart, but the
                        // Recovery dialogue only shows the first restart delay (0 minutes)
                        rc.RestartService(delayInMinutes: 1); 
                        // Corresponds to ‘Subsequent failures: Restart the Service’
                        rc.RestartService(delayInMinutes: 5);
                        // Corresponds to ‘Reset fail count after: 1 days’
                        rc.SetResetPeriod(days: 1); 
                    });
