[GitHub] codelipenghui opened a new issue #3131: Consumer stop receive messages from broker

codelipenghui opened a new issue #3131: Consumer stop receive messages from broker
URL: https://github.com/apache/pulsar/issues/3131
 
 
   #### Actual behavior
   
   A process subscribe a topic with 2 subscriptionName. After a few hours, we found backlog of 1 subscriptionName growing continuous, then check the broker stats:

   Stats of unackedMessages and availablePermits looks weird, i don't understand why both of them is 0 at the same time.
   
   Then make the heap dump of client, but did not find anything abnormal. I'm already upload the heap dump to slack:

   #### System configuration

   **Pulsar Client version**: 2.2.0
