I have a dockerized web application that contains 3 containers (Django/ PostgreSQL/Elasticsearch), The indices of the Elasticsearch are indexed depending on the Django database models using a library called Django-Elasticsearch-dsl. Everything is working good on my localhost and indexing of Django database to the Elasticsearch container is working without any errors. When I deployed my application on an AWS EC2 instance It works well for the first few times and then an error occurs after indexing more data (BulkIndexerror). I have changed my instance type and reached t2.2xlarge (I have started with t2 small and gradually reached t2.2x large) and when I change the instance type it works well for a period of time and after time the same error occurs

in my localhost when I run `python manage.py search_index --rebuild` this appears to me:

```auto

```

on AWS EC2 instance:

```auto

System check identified some issues:

    class Django:

```

So how can I solve this bugs?
