       @Test
       public void testSub() throws PulsarClientException, InterruptedException {
           String serviceUrl = "pulsar://172.32.149.121:6650,172.32.148.243:6650";
           PulsarClient client = PulsarClient.builder().serviceUrl(serviceUrl).lookupTimeout(-1, TimeUnit.SECONDS).build();
   
           CountDownLatch countDownLatch = new CountDownLatch(1);
           List<ConsumerThread> consumers = new ArrayList<>();
           int consumerCount = 20;
           ExecutorService executor = Executors.newFixedThreadPool(20, new ThreadFactoryBuilder().setNameFormat("PulsarTest").build());
           for (int i = 41; i <= 60; i++) {
               ConsumerThread consumerThread = new ConsumerThread(client, i);
               executor.execute(consumerThread);
               consumers.add(consumerThread) ;
           }
           countDownLatch.await();
       }
   
   By using this test case, the problem can be reproduced.
