  It's strange that your code trying to resolve MyModule. Why? Do you have a dependency to MyModule class, which is normally should not be? Also, is that a web application? What is delay between job executions?

  Hi,

  No, I have no dependency to MyModule. The project is a class library, that is deployed via the web application that comes with the template. MyModule implements AbpModule. The main goal of the module is to execute recurring jobs (some should execute every 2 minutes, some every hour). The jobs are registered in hangfire and access code in .Application project. It is strange because the jobs run fine for 30 minutes. After that it seems like castle "forget" the reference.

  I have done some refectoring to make the problem more clear. I seperate the job into an own class:

  public class JobDefinition : ITransientDependency
      {
          private readonly IIocResolver _iocResolver;
  
          public JobDefinition(IIocResolver iocResolver)
          {
              _iocResolver = iocResolver;
          }
  
          [DisplayName("Import qutations from url {0}")]
          [AutomaticRetry(Attempts = 0, OnAttemptsExceeded = AttemptsExceededAction.Delete)]
          public void QutationImportServiceJobDefinition(string tenant, string url)
          {
              var qutationImportService = _iocResolver.Resolve<IQutationImportService>();
              qutationImportService.Start(tenant, url);
          }
      }
  

  Here is the definition of the module:

  [DependsOn(typeof(AbpHangfireModule))]
      public class MyModule : AbpModule
      {
          public override void Initialize()
          {
              IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());
         
  
              Configuration.BackgroundJobs.UseHangfire(
                  configuration => { configuration.GlobalConfiguration.UseSqlServerStorage("Default"); });
          }
  
  
          public override void PostInitialize()
          {
              base.PostInitialize();
  
              var jobDefinition = new JobDefinition(IocManager);
  
  
                  //Every 2 minutes
                  RecurringJob.AddOrUpdate($"Job for {tenant}",
                      () => jobDefinition.QutationImportServiceJobDefinition("---", "http://google.com"),
                      "*/2 * * * *");
           
          }
      }
  

  The exception is:

  JobDefinition jobDefinition = Activate<JobDefinition>(); jobDefinition.QutationImportServiceJobDefinition();

  Failed An exception occurred during processing of a background job.

  Castle.MicroKernel.ComponentNotFoundException

  No component for supporting the service JobDefinition was found Castle.MicroKernel.ComponentNotFoundException: No component for supporting the service JobDefinition was found at Castle.MicroKernel.DefaultKernel.Castle.MicroKernel.IKernelInternal.Resolve(Type service, IDictionary arguments, IReleasePolicy policy) at Castle.MicroKernel.DefaultKernel.Resolve(Type service, IDictionary arguments) at Castle.Windsor.WindsorContainer.Resolve(Type service) at Abp.Dependency.IocManager.Resolve(Type type) at Abp.Hangfire.HangfireIocJobActivator.ActivateJob(Type jobType) at Abp.Hangfire.HangfireIocJobActivator.HangfireIocJobActivatorScope.Resolve(Type type) at Hangfire.Server.CoreBackgroundJobPerformer.Perform(PerformContext context) at Hangfire.Server.BackgroundJobPerformer.<>c__DisplayClass8_0.<PerformJobWithFilters>b__0() at Hangfire.Server.BackgroundJobPerformer.InvokePerformFilter(IServerFilter filter, PerformingContext preContext, Func1 continuation) at Hangfire.Server.BackgroundJobPerformer.<>c__DisplayClass8_1.<PerformJobWithFilters>b__2() at Hangfire.Server.BackgroundJobPerformer.PerformJobWithFilters(PerformContext context, IEnumerable1 filters) at Hangfire.Server.BackgroundJobPerformer.Perform(PerformContext context) at Hangfire.Server.Worker.PerformJob(BackgroundProcessContext context, IStorageConnection connection, String jobId)

  The application runs on the latest version of ABP. The secneario is the same deployed to my local IIS/ to azure. The application is set to "run always".

  Do you have any idea why it "forgets" the reference? If you have any other idea how to register jobs in a seperate module that are executed with hangfire I can also follow this guidance.

  The only probability I can think for now is your web app is being shutdown. To ensure that, override Shutdown method in MyModule and log something to see if it happens.

  Hi hikalkan,

  During the last month I traced the issue a lot. However, I cant find the root of the problem. Here is my scenario:

  1. I debug (on my local IIS) or deploy the application to azure
  2. Azure app service is configured to dont shut down
  3. When using hangfire and the job is executed and sometime I receive the mentioned error and sometime it works (50/50 chance)
  4. When the error appear I restart the iis. Sometimes it works and sometimes not.

  Do you have any idea how to get rid of it?

  You should keep your application alive. Have you seen that: <a class="postlink" href="http://docs.hangfire.io/en/latest/deployment-to-production/making-aspnet-app-always-running.html">http://docs.hangfire.io/en/latest/deplo ... nning.html</a>

  The application is alive and azure is configured to dont shut down. The problem exist randomly if I start debugging or deploy a new version. I think for some reasons it randomly failed to register the dependencies
