In a Saas app, we want order imports to run in serial for each tenant. But multiple order imports can run concurrently for different tenants (up to a point). Then also runs other types of jobs that again I’d like to run serially by tenant, but multiple tenants can run concurrently.

I am using Hangfire library to do job in my asp.net core C# application, the library work normally every day, but in the Friday and Saturday not work, what is the problem?
