BewareMyPower commented on issue #11413:
URL: https://github.com/apache/pulsar/issues/11413#issuecomment-891663001


   The main exception stack was introduced from https://github.com/apache/bookkeeper/pull/2587, which added an error level log in `shouldRetryOnException`.
   
   ```bash
   $ grep ERROR ~/logs-1.txt
   04:12:47.367 [client-scheduler-OrderedScheduler-0-0] ERROR org.apache.bookkeeper.clients.impl.internal.RootRangeClientImplWithRetries - Reason for the failure {}
   04:12:48.377 [client-scheduler-OrderedScheduler-1-0] ERROR org.apache.bookkeeper.clients.impl.internal.RootRangeClientImplWithRetries - Reason for the failure {}
   04:12:49.666 [client-scheduler-OrderedScheduler-0-0] ERROR org.apache.bookkeeper.clients.impl.internal.RootRangeClientImplWithRetries - Reason for the failure {}
   04:12:50.952 [client-scheduler-OrderedScheduler-1-0] ERROR org.apache.bookkeeper.clients.impl.internal.RootRangeClientImplWithRetries - Reason for the failure {}
   ```
   
   Other exception stacks are thrown during ZK client's close, like
   
   ```
   04:12:42.868 [main-SendThread(127.0.0.1:2181)] WARN  org.apache.zookeeper.ClientCnxn - An exception was thrown while closing send thread for session 0x1000001599a0005.
