saosir opened a new issue #9028:
URL: https://github.com/apache/pulsar/issues/9028
**Describe the bug**
Both `PartitionedConsumerImpl` and `ConsumerImpl` have member variable
`unAckedMessageTrackerPtr_` (class UnAckedMessageTrackerEnabled), and
`PartitionedConsumerImpl` is composed of `ConsumerImpl`. If the acknowledgement
times out, they will send redeliverMessages repeatedly,
`MultiTopicsConsumerImpl` has same problem.
see #8606
**To Reproduce**
1. subscribe a partitioned topic and set UnAckedMessagesTimeoutMs
```cpp
Consumer consumer;
ConsumerConfiguration consumerConf;
consumerConf.setUnAckedMessagesTimeoutMs(11000); // must >= 10000
consumerConf.setTickDurationInMs(11000);
Result result = client.subscribe("my-topic", "consumer-1", consumerConf,
consumer);
```
2. recevie a msg from partitioned topic and not do acknowledge
```cpp
Message msg;
consumer.recevie(msg)
sleep(20000);
```
3. sleep 20000ms to trigger `redeliverMessages` repeatedly
```cpp
sleep(20000);
```
**Expected behavior**
Only one `redeliverUnacknowledgedMessages` should be sent in
`PartitionedConsumerImpl`
