      Description

      Reproduction steps:
      1. Start a multi-broker quorum (e.g. 3 brokers)
      2. Create a multi-replica topic (e.g. 3 replicas)
      3. Start an async performance producer with a fixed number of messages to produce
      4. Force kill a partition leader broker using SIGKILL (no clean shutdown) - make sure you kill it during actual writes
      5. Wait for the producer to stop
      6. Read from the topic from the beginning - there will a small amount of duplicate messages
