[GitHub] [pulsar] shibd opened a new issue, #15224: Producers in MessageDeduplication may not expire

shibd opened a new issue, #15224:
URL: https://github.com/apache/pulsar/issues/15224

   **Describe the bug**
   
   In the current `MessageDeduplication` implementation, when the producer is disconnected, the producer will be added to the inactiveProducers collection, waiting to be expired and deleted.
   
   But before the expired deletion, if the broker restarts and these producers are no longer reconnected, then these producers will never be expired and deleted
   
   **To Reproduce**
   1. Change messageDeduplication config on `standalone.conf`:
   ```
   brokerDeduplicationEnabled=true
   brokerDeduplicationMaxNumberOfProducers=10000
   brokerDeduplicationSnapshotFrequencyInSeconds=10
   brokerDeduplicationSnapshotIntervalSeconds=60
   brokerDeduplicationEntriesInterval=10
   brokerDeduplicationProducerInactivityTimeoutMinutes=2
   ```
   3. Start pulsar standalone.
   4. Create some produces and send messages.
   5. Close or stop these producers.
   6. Restart broker.
   
   **Expected behavior**
   
   After waiting 2 minutes, all producers expired and delete.
   
   **Actual behavior**
    These producers will never be expired and deleted.
   
   **Desktop (please complete the following information):**
    - OS: [e.g. iOS]
   
   **Additional context**
   Here is another question about the existence in MessageDeduplication, One of the issues references #15204.
