[GitHub] [pulsar-client-cpp] BewareMyPower opened a new issue, #55: [Bug] Producer was not clean up after closed
BewareMyPower opened a new issue, #55:
URL: https://github.com/apache/pulsar-client-cpp/issues/55
### Search before asking
- [X] I searched in the [issues](https://github.com/apache/pulsar-client-cpp/issues) and found nothing similar.
### Version
- OS: Ubuntu 20.04
- Pulsar: 2.10.1
- C++ client: master 7f7653b
### Minimal reproduce step
```c++
#include <pulsar/Client.h>
#include <chrono>
#include <thread>
using namespace pulsar;
int main() {
Client client("pulsar://localhost:6650");
while (true) {
Producer producer;
auto result = client.createProducer("my-topic", producer);
if (result != ResultOk) {
break;
}
producer.close();
std::this_thread::sleep_for(std::chrono::milliseconds(500));
}
client.close();
}
```
### What did you expect to see?
The memory usage should be stable.
### What did you see instead?
The program above just create producers in loop. However, the memory usage keeps increasing after some time (in my local env, after the 27th producer is created, each time a producer is created and closed, 16KB memory usage will be increased)
Here is a simple script to detect memory usage on Linux (assuming the program name is `SampleProducer`):
```bash
#!/bin/bash
set -ex
PROC_ID=$(ps aux | grep "SampleProducer" | grep -v grep | awk '{print $2}')
if [[ $PROC_ID ]]; then
for i in {1..100}; do
cat /proc/$PROC_ID/status | grep VmData
sleep 1
done
fi
```
### Anything else?

With patch from #54, the memory keeps stable (even if I sent a message in each iteration), see
