bug?

Hello,
I use Hangfire for be background jobs on our .net project. Everything was good until i’ve migrated to .net core 2.1.
After that OutOfMemory exception is occurred when starting on ubuntu/linux. On Windows it works fine.
The same for 16.04 and 18.04 x64 versions
Here is stack trace:
Failed to process the job ‘7b533caf-bbf5-4e14-82ce-630940bdfb5f’: an exception occurred. Retry attempt 1 of 10 will be performed in 00:00:44.
System.OutOfMemoryException: Exception of type ‘System.OutOfMemoryException’ was thrown.

Hangfire.Core version 1.6.20
Hangfire.AspNetCore version 1.6.20
Hangfire.MemoryStorage 1.5.2

Code for ConfigureServices:
public void ConfigureServices(IServiceCollection services)
{
…

			services.AddHangfire(config => config.UseMemoryStorage(new MemoryStorageOptions
			{
				
			}));
		}

Code for Configure method:

...
var options = new BackgroundJobServerOptions
			{
				SchedulePollingInterval = TimeSpan.FromSeconds(Constants.QueueJobInterval)
			};

			app.UseHangfireServer(options);

			app.Run(async (context) =>
			{
				await context.Response.WriteAsync("Worker started");
			});


			BackgroundJob.Schedule(() => serviceProvider.GetService<QueueJob<EmailQueueMessage>>().ProcessMessages(), TimeSpan.FromSeconds(Constants.QueueJobInterval));
...

Any help will be appreciated

Issue has been solved. Problem was in generic types for running scheduled jobs
BackgroundJob.Schedule(() => serviceProvider.GetService<QueueJob<EmailQueueMessage>>().ProcessMessages(), TimeSpan.FromSeconds(Constants.QueueJobInterval));

Need to replace something like this to remove generic types for runner:
var jobRunner = serviceProvider.GetService<JobRunner>(); BackgroundJob.Schedule(() => jobRunner.ProcessEmailQueueJob(), TimeSpan.FromSeconds(Constants.QueueJobInterval));
