### 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 CentOS Linux release 7.8.2003 (Core) ### RocketMQ version RocketMQ 5.0.0 ### JDK Version jdk1.8.0_131 ### Describe the Bug Queue diffTotal down to 0 and rollback, without any error. Can not find any clue by log. RocketMQ Server should give me some tip in log. ### Steps to Reproduce Message in Queue 0 as:  I used the rocketmq-client to consume queue message. <groupId>org.apache.rocketmq</groupId> <artifactId>rocketmq-client</artifactId> <version>5.0.0</version>  After executed the program, queue 0 diffTotal was down to 0. No exception in the client log: 2023-06-30 11:05:09.486 INFO [10728] [MQClientFactoryScheduledThread] [o.a.r.c.c.s.RemoteBrokerOffsetStore#?:?] - [persistAll] Group: message-device-group ClientId: 172.27.64.1@10728#91880700965800 updateConsumeOffsetToBroker MessageQueue [topic=message_topic, brokerName=broker-a, queueId=0] 35561 But the diffTotal back to 22667 again,after a while. I stop the consumer program and rerun, still the same result I could not find errors in the logs on server. The process looks like the rollback: update the offset in server memory, and rollback the offset. ### What Did You Expect to See? Any exception shoud be in log to help solve problem. ### What Did You See Instead? I can not find any useful log info to the problem. ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
