Background job is not re-executed #8894 | Support Center

peopleteq created 4 years ago

I have issue with Background job tries. Job are created in AbpBackgroundJobs table and executed once. After job failed, job record in the table is not updated: NextTryTime is still equesl to CreationTime and TryCount is 0. Even 1 day after failed jobs are in db and not updated.

Log:

You can see 2 exceptions there. They are AbpDbConcurrencyException. First occured during job precessing. The second - TryUpdate background job.

Code of Execute method of Background Job

    public override async void Execute(DefectPhotoUploaderBackgroundJobArgs args)
        {
            using (var unitOfWork = UnitOfWorkManager.Begin())
            {

                string photoUrl = await _cloudStorage.UploadFileAsync(args.Image, "image_123.jpg");

                await _backgroundJobManager.EnqueueAsync<DefectPhotoUrlSaverBackgroundJob, DefectPhotoUrlSaverBackgroundJobArgs>(     <<< I think first exception occured because of this operation. There is one more backgroud job created
                    new DefectPhotoUrlSaverBackgroundJobArgs()
                    {
                        InspectionGuid = args.InspectionGuid,
                        DefectId = args.ProductInstanceInspectionDefect.DefectId,
                        PhotoUrl = photoUrl
                    });

                unitOfWork.Complete();                                                                                                                                                                                <<< SaveChanges called. it is failed with the exception
            }
        }                                                                                                                                                                                                                             <<< Job Manager tryes to update status of failed job and gets the exception.

it is important to mention that AbpBackgroudJobs table contains many of records (1000+).

Can you please to help with the issue?

Also can you please answer on questions about manager:

How often do Manager look for job ready be executed?
How many jobs executed in one loop?

ANZ version: 8.0.0

Thanks

Hi,

Could you chante unitOfWork.Complete(); to await unitOfWork.CompleteAsync(); and try again ?

Next try time is calculated here https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp/BackgroundJobs/BackgroundJobManager.cs#L159. If ABP couldn't update the Job info, there must be a warning in the log files about this.

Hi @ismcagdas ,

I applyed your change, but that did not help. Also I realsied that sometimes a job is abandoned immediatly right after it's created. The job on the picture was not called. I checked this during debug.

Can you please say why that happens?

Hi,

IsAbandoned is set to true in two places in this class https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp/BackgroundJobs/BackgroundJobManager.cs. In both cases, there must be a warning log written to your log file. Did you find such warning message in server side Log file ?

Hi,

There was no warning. But I will try to repeat test case again.

Now I am getting TryUpdate job warning again

The job

On the picture you can check time of the job and compare that with time on log (+7 timezone). As you can see the log does not have any messages regarding the job. Also my job writed debug line into log, to check that the job was executed. The line is missing in the log too.

Hi @peopleteq,

Do you know exactly when this happens ? If so, we can reproduce it on our side. If you can share your background job class and where you initiate it with [email protected] we can also try to reproduce it.

Thanks,
