[I] [Bug] PopBufferMergeService 消息订阅者关系被移除 [rocketmq]
MarvinYu opened a new issue, #9318:
URL: https://github.com/apache/rocketmq/issues/9318
### 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.
- [x] I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ.
### Runtime platform environment
Linux or other
### RocketMQ version
>= 5.0.0
### JDK Version
_No response_
### Describe the Bug
PopBufferMergeService#scanGarbage 代码
```java
if (System.currentTimeMillis() - entry.getValue().getTime() > minute5) {
POP_LOGGER.info("[PopBuffer]remove long time not used sub {} of topic {} in buffer!", cid, topic);
iterator.remove();
continue;
}
```
对于一些开发和测试环境而言，因为消息比较少，topic与消费者订阅关系很容易被移除，然后出现消费者消息出现skip的情况。
### Steps to Reproduce
消息发送者一天发送了5条消息，但是最终消费者只消费到其中三条
### What Did You Expect to See?
消费者消息不丢失
### What Did You See Instead?
消费者消息不丢失
### Additional Context
