### 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 ### RocketMQ version Broker: 4.8.0 Client: 4.9.3 ### JDK Version java version "1.8.0_121" ### Describe the Bug A topic has 4 brokers and 16 queues totally. One consumer group has two instance. After the issue observed, find the cg lag keeps growing. We identify two queues in one broker have the issue. The offset of these two queues has no change. We use tcpdump check the message sent from client to broker and found the offset sent from client always use the old value. Then we check the dump file of client and find the offset in dump of these two queues use old value. At the same time we find consumer still consume message successfully from all queues. Since it's production environment we use admin tool reset offset. Now the problem has gone. ### Steps to Reproduce Don't know how to reproduce it currently. Some clues 1. Our client started in docker container. 2. Due to node issue we have to restart all nodes one by one. 3. The message of that offset was consumed by one old container but this message is still pulled by new started container. 4. We use pushConsumer model. 5. Other 14 queues offset is normal ### What Did You Expect to See? No lag and offset is normal ### What Did You See Instead? Lag keep growing and offset maintain old value ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
