[GitHub] [pulsar] klevy-toast commented on issue #15679: Topic rebalances cause consumers with receiverQueueSize=0 to get stuck

klevy-toast commented on issue #15679:
URL: https://github.com/apache/pulsar/issues/15679#issuecomment-1135086108

   I have made more accurate local reproduction steps with docker / kotlin which should be straightforward to run with this test file: https://gist.github.com/klevy-toast/38d737c8abdbeb8d352c7617e4a96cfa
   
   It appears to be a bug specifically related to the `ZeroQueueConsumer`'s `receiveAsync`, after a topic has been unloaded while the consumer is connected. Using `receive` instead does not get stuck. I verified that the bug occurs with both 2.7.2 and 2.9.2
   
   @mattisonchao please let me know if you have any trouble reproducing this. Thank you!
