RabbitMQ loads RAM heavily, how can it be optimized correctly?

Question

C++ / C#

The system is configured to transfer files (.jpg), about 2k files are processed, Rabbit closes all connections and stops receiving messages, bytes of files are transferred in messages, the question is why rabbitmq does not delete them, because the system no longer needs them, the messages were processed successfully

Answer 1

Instead of tried not to transfer pictures through queue? Rabbitmq is still not designed for such a load.
