[GitHub] [pulsar] mingfang opened a new issue #4964: Broker unable to restart

mingfang opened a new issue #4964: Broker unable to restart
URL: https://github.com/apache/pulsar/issues/4964
 
 
   I have a working Broker cluster with 3 replicas.
   When I bounce any of the replicas, then they fail to start.
   Here is the error 
   ```
