            Job seems to run as Fire and Forget. Database activity continues for up to 10 minutes after success status
            Asked 2022-Apr-07 at 13:46

            I am debugging this hangfire service job call and can't figure out why hangfire is reporting a completed state while the stored procedures being called are continuing to run for up to ~10 minutes later. The parallel loop is running a stored procedure against up to 200 databases.

            The first image below shows the hangfire status (success in ~40 seconds), meaning the job function completed. The second image shows the Stored Procedures issued form the loop still running for many minutes later. As far as I know, hangfire will report success when the job function completes, report timeout after a max wait, or report error is an exception occurs. I don't see how this function could be exiting in 6 seconds if all tasks are awaited.

            Hangfire reports success in 40 seconds

            Long Running Query Detection shows queries from the job still running and falling in and out of blocking state many minutes later. The commands starting with --===================== represent the SP running against many different databases.

            My thoughts are that Parallel.ForEach does not await for the async lambda so PerformServiceWork ends before each lambda is still running.

            Try to use instead Task.WhenAll and await on it.

            As I recall Parallel.ForEach is more related to Threading while Tasks are an abstraction over Threads.

            I have a job filter that I want to apply to every job. What I want to do is: when the job fails (goes to FailedState, which happens when the max retry attemps exceed OR it is thrown in that state manually), I want to log a custom, user-friendly exception message to the database (my custom table).

            Mass Transit: Using AWS SQS and Job Consumers
            Asked 2022-Mar-09 at 02:22

            Currently we're using Hangfire for scheduling and running long lived tasks. We need these tasks to be able to be retried in the event of an ungraceful shutdown, which Hangfire handles for us.

            We're looking to try and move to a producer/consumer model and I've built a basic prototype with Masstransit and AWS SQS, but I have some concerns about how to handle the event of a task being processed during an ungraceful shutdown.

            I understand that eventually the SQS visibility timeout will expire and the queued item will be picked up for processing again, but setting that timeout isn't trivial as the length of tasks can be quite varied and I'd prefer if the task could immediately resume/retry processing when the application starts up again.

            I got reading about Job Consumers and they seemed to be better fitted to this type of scenario, but all the examples I've seen are using RabbitMQ. Wondering if it's possible/appropriate to do this using SQS, or if there's a better approach?

            Thank you for taking the time to read this question :)

            ANSWER

            Answered 2022-Mar-09 at 02:22

            MassTransit will extend the visibility timeout as long as the consumer is still running.

            I believe SQS has an upper-limit of something like 12 hours, but you should look it up and find out.

            Job Consumers have significantly greater requirements (sagas, temporary queues, etc.) and SQS is really annoying about not having auto-delete/expiring queues, so I'd stick to a regular consumer if you can swing it.

            Running recurring job inside Startup
            Asked 2022-Mar-03 at 10:01

            If I have a recurring job that will be run daily inside the .net core application. For that purpose, I'm thinking to use the Hangfire library.

            My question is: will placing this code for executing this daily job here in the Configure method be the most logical place or you would suggest something else?

            Asp.net core provide a IHostApplicationLifetime which provide the methods which could be triggered when the application host has fully started, when the application host has performed a graceful shutdown, when the application host is performing a graceful shutdown.

            I think you could put this method inside the IHostApplicationLifetime's ApplicationStarted method will be good.

            More details about how to use it, you could refer to this article.

            If it's an asp.net core application (not just old school asp.net) there is no problem with task deadlock. SynchronizationContext (which can cause deadlock without ConfigureAwait(false)) is null in asp.net core. There isn’t a SynchronizationContext in ASP.NET Core.

            Also without Task.Run - CallApiAndUpdateSthAsync will be executed on your current thread until the first await inside. With Task.Run - entire CallApiAndUpdateSthAsync will be executed out of your main execution. You can fix it with adding Task.Yield in the beginning of CallApiAndUpdateSthAsync.

            Can Hangfire schedule jobs do this?
            Asked 2022-Jan-10 at 11:08

            I am evaluating Hangfire for an upcoming ASP.net Core project that has several scheduled and reoccurring tasks that need to execute independently of users clicking on web pages. I know that HangFire can do this if the web application is started because a request has come in. I need to know whether or not HangFire can execute a scheduled task between being rebooted and the first web request coming in.

            Example: Web server is rebooted at 11pm, and no web requests will come in to cause the web server to spin up until 5am the next morning. A scheduled task needs to be performed at 1AM. Will Hangfire execute this task even though the web application hasn't been started by an incoming request?

            If it can, is there a certain setup I need to do to allow this?

            Details, if needed: We are going to be using Kestrel hosted in a windows service and sitting behind an NGINX reverse proxy. This setup could be modified if needed to make HangFire meet this requirement.

            When running under IIS it would be a real problem, see Making ASP.NET application always running

            But it should not be problem for ASP.NET CORE with kestrel, see

            It is not necessary for ASP.NET Core, because application is exposed by a console application that it already always on – there are no timeouts, no suspends and other optimization techniques yet. All you need to do is to use supervisor as written in the official docs for Linux, or use Windows Service with automatic start time, when running on Windows.
