   ### Before Creating the Bug Report
   
   - [X] I found a bug, not just asking a question, which should be created in [GitHub Discussions](https://github.com/apache/rocketmq/discussions).
   
   - [X] I have searched the [GitHub Issues](https://github.com/apache/rocketmq/issues) and [GitHub Discussions](https://github.com/apache/rocketmq/discussions)  of this repository and believe that this is not a duplicate.

   ### Runtime platform environment
   
   All platform
   
   ### RocketMQ version
   
   4.9.3 ～ lastest, after #3657
   
   ### JDK Version
   
   All versions
   
   ### Describe the Bug
   
   When topics are created and deleted frequently, a JVM crash occurred. Analysis revealed that when a topic is deleted, the file is unmapped. During this time, the ReputMessageService dispatches the consumeQueue and writes to the mmap file, which may cause the JVM to crash.
   
   ### Steps to Reproduce
   
   Start the broker
   Start the producer to send continuously
   While sending, use the admin to delete the topic
   Finally, the broker crashes, and the exception stack trace is consistent with the one online
