BewareMyPower opened a new issue #8230:
URL: https://github.com/apache/pulsar/issues/8230


   **Describe the bug**
   If the reader 
   
   **To Reproduce**
   Steps to reproduce the behavior:
   
   Giving the following client code:
   
   ```c++
   #include <pulsar/Client.h>
   #include <pulsar/Reader.h>
   
   #include <lib/LogUtils.h>
   
   DECLARE_LOG_OBJECT()
   
   using namespace pulsar;
   using namespace std;
   
   int main(int argc, char* argv[]) {
       Client client("pulsar://localhost:6650");
   
       ReaderConfiguration readerConf;
       readerConf.setSubscriptionRolePrefix("reader-sub");
       readerConf.setReaderName("reader");
   
       Reader reader;
       auto result = client.createReader("my-topic", MessageId::earliest(), readerConf, reader);
       if (result != ResultOk) {
           LOG_ERROR("create reader failed: " << result);
           return 2;
       }
   
       int numReceived = 0;
       while (true) {
           bool available;
           auto result = reader.hasMessageAvailable(available);
           if (result != ResultOk) {
               break;
           }
       }
   
       client.close();
       return 0;
   }
   ```
   
   1. Run the pulsar standalone:
       ```bash
       $ bin/pulsar-daemon start standalone
       ```
   2. Run the above client
   3. Kill the standalone by `SIGKILL`:
       ```bash
       $ cat bin/pulsar-standalone.pid | xargs kill -9
       ```
   
   However, the client would never return because it stuck on `hasMessageAvailable`. But if the standalone was terminated by `bin/pulsar-admin stop standalone`, the client would exit normally.
   
   It looks like that the client didn't detect the close of broker.
   
   **Expected behavior**
   `Reader::hasMessageAvailable` should return `ResultNotConnected` even if broker was terminated by force.
