The segment file continues to expand indefinitely.

Describe the bug

I am using rabbitmq 3.13.6, in 3-node cluster mode, and the queue is a quorum queue. In actual use, I found that the segment is always growing and the old files are not automatically cleaned up.

Reproduction steps

1.Use quorum queue.
2.Submit a large number of messages concurrently and do not ack them completely, simulating the scenario of message accumulation.
...

Expected behavior

The number and size of segment files remain stable.

If you don't acknowledge the messages, they have to be stored by the queue (they are not consumed). They are stored in segment files: https://www.rabbitmq.com/docs/quorum-queues#segment-file-truncation

If you believe there's a genuine issue then:

1. you must provide more details
2. you must provide more specific reproduction steps (publishing messages without consuming them will create additional segment files by design)
3. you need to test on RabbitMQ 4.1. RabbitMQ 3.13 is only supported for paying customers at this point

@MiChongGET you must provide a set of steps for us to reproduce this behavior against 4.1.0. 3.13.x is out of community support.

In addition, 4.1.0 includes tweaks that make quorum queues clean up segment files more often. It should be mentioned in the release notes. There are several existing discussions on the topic in this very repository.
