I have created a new app through CLI(0.18) and regenerated the migration files to use PostgreSQL.
Test 1:
Run the app without debugging, and the process(IIS Express Worker Process) memory was ~340mb.
Refresh the home page, and the memory increased ~3mb. And keep refreshing the same page, the memory went up steadily(3mb/refresh).
Test 2:
Start the app, and the memory was ~340mb. Do nothing for 15 minutes and the memory went up to 390mb.

Thanks for reporting. Debug mode may not reflect the real memory usage. We are using ABP framework in some live web sites (abp.io, for example) and didn't see such a continuously increasing memory usage.
However, your case can be true, so we will also check it. If you find anything about that, please share.
Thanks for reporting.

BackgroundJobWorker.DoWork() gets BackgroundJobStore instance every 5000ms cause memory leak, because BackgroundJobStore will get a DbContext instance every time.
This code will allocate about 200MB of memory per hour, the temporary solution is disable BackgroundJobs completely, or use InMemoryBackgroundJobStore (also allocate memory but much less than BackgroundJobStore).
- memory profile with
BackgroundJobStore(mongodb):
- memory profile with

Thanks @lonwern for the additional info. I will check the background job problem & fix.

I tried background job worker in a console application and can't see a memory leak.
- Inserted 100.000+ jobs to the database.
- Changed job poll period to 1ms.
- Runned ~5 minutes.
- Memory size remains 35M to 40 MB (when it increased to 40MB, automatically decreases to ~35MB by GC).
- I run the application with CTRL+F5.
As you can see in the code, we are using ServiceScopeFactory.CreateScope() to create & dispose a scope, so allocated memory (including DbContext) is being cleared by the end of the using statement.
Can it be different in a web application? I don't suppose.

I tried version 0.21, and the memory looks stable. Maybe I should close this issue. @hikalkan, how do you think?

Abp recently solved some problems and also upgraded to net core 3.0. Perhaps the memory leak problem no longer exists. :)
