Hello,

The API Server is running in Azure App Services and we are also using Hangfire to execute some long running tasks. The background jobs consistently encounter OutOfmemoryException and this results in App Service going down. We have tried to disable Hangfire and the default ASP.Net Zero Background Manager in Production but the exceptions still occur. Please find below the exception details

Can you please help us in getting answers to following two questions?

  1. How to configure Hangfire in ASP.Net Zero code to run on a separate machine/server? Currently, the Hangfire server is configured in the main applicaiton and we also use Repository classes within Hangfire job code.
  2. If the issue is due to some memory leak problems with Hangfire then how can we use some other Background Job Manager?

Thanks in advance.

    Hi @shridhar.mole

    1. You can create a new empty application and add Abp NuGet packages to this project and enable Hagfire in it.
    2. We are also hosting our demo on live and haven't faced such a problem until now.

    Could you share your related BackgroundJob code with us ? You can also try to analyze your app using a memory profiler to find this problem. Using Visual Studio to memory usage and jMeter to initiate heavy requests might help you to identify the problem locally.

    Hi @ismcagdas

    Thanks for the feedback. I will try the memory profiling as well as check if we can share the BackgroundJob code with you.

    Meanwhile, we have disabled Hangfire and Abp BackgroundJobManager from everywhere in the code, removed hangfire schema from DB, ensured that AbpBackgroundJobs table is empty. But the app service still gets OutOfMemoryException after it is running for some time. This is irrespective of whether the application is being actively used or not. Can you please guide us in resolving this issue at the earliest? Would upgrading ABP version help (current version is 6.2)?

    Thanks.

    Hi @shridhar.mole

    It seems like there is a memory leak somewhere. Do you know how long does it take your app to get this exception ? You can deploy it to your local server and leave it open for a while and in that period you can analyize your app using a memory profiler tool.

    Hi,

    The issue had occurred due to EF Core Logging feature that was enabled in production by mistake. This resulted in generating too many logs and ultimately causing out of memory exception. Thanks for your help.
