We are encountering the same issue with the Pulsar `2.8.1` codebase. Here are my observations: 1. The occurrence of this issue for a specific broker/topic/subscription is unpredictable. 2. This issue only arises in our test environment (with limited resources) after the overload shedder is triggered: ``` 2023-05-07T06:18:15.865Z [pulsar-load-manager-1-1] INFO org.apache.pulsar.broker.loadbalance.impl.ModularLoadManagerImpl - [Overload shedder] Unloading bundle: platform/dp/0x40000000_0x80000000 from broker 172.17.5.176:8080 ``` The log for the new topic owner broker indicates that the managed-ledger initializes successfully, but it doesn't load any cursor. <img width="1665" alt="image" src="https://user-images.githubusercontent.com/5058708/236774130-cf400618-4a2b-421f-ac9f-f99e0b5afd9d.png";> When a user attempts to consume this topic, they'll encounter the following error: `org.apache.zookeeper.KeeperException$BadVersionException: KeeperErrorCode = BadVersion for /managed-ledgers/platform/dp/persistent/resume.complete.result-ai.bert.cv.change.nlp.sub-DLQ/ai.bert.cv.change.nlp.sub` 3. Unload the topic resolves the problem. -- This is an automated message from the Apache Git Service.
