BewareMyPower opened a new issue, #261: URL: https://github.com/apache/pulsar-client-cpp/issues/261
### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar-client-cpp/issues) and found nothing similar. ### Version - Pulsar 2.11.0 - Pulsar Client 3.2.0 candidate 1: https://dist.apache.org/repos/dist/dev/pulsar/pulsar-client-cpp/pulsar-client-cpp-3.2.0-candidate-1 ### Minimal reproduce step ```c++ #include <pulsar/Client.h> using namespace pulsar; int main(int argc, char *argv[]) { // The server ran inside WSL2 on Windows Client client("pulsar://172.22.48.50:6650"); Producer producer; auto result = client.createProducer("persistent://public/default/test-topic", producer); if (result != ResultOk) { std::cerr << "Failed to create producer: " << result << std::endl; return 1; } client.close(); return 0; } ``` The Pulsar standalone ran on the Ubuntu 20.04 WSL2 subsystem whose IP is `172.22.48.50`. ### What did you expect to see? No error logs appeared. ### What did you see instead? There was an error log when closing the client: ``` 2023-04-28 22:08:06.875 INFO [12684] D:\a\pulsar-client-cpp\pulsar-client-cpp\lib\ProducerImpl:755 | [persistent://public/default/test-topic, standalone-5-42] Closing producer for topic 000001ED65D25180 2023-04-28 22:08:06.877 INFO [11036] D:\a\pulsar-client-cpp\pulsar-client-cpp\lib\ProducerImpl:719 | [persistent://public/default/test-topic, standalone-5-42] Closed producer 0 2023-04-28 22:08:06.878 INFO [3112] D:\a\pulsar-client-cpp\pulsar-client-cpp\lib\ClientConnection:1205 | [172.22.48.1:5376 -> 172.22.48.50:6650] Connection disconnected 2023-04-28 22:08:06.878 INFO [3112] D:\a\pulsar-client-cpp\pulsar-client-cpp\lib\ClientConnection:1205 | [172.22.48.1:5377 -> 172.22.48.50:6650] Connection disconnected 2023-04-28 22:08:06.878 ERROR [11036] D:\a\pulsar-client-cpp\pulsar-client-cpp\lib\ClientConnection:616 | [172.22.48.1:5376 -> 172.22.48.50:6650] Read operation failed: 由本地系统中止网络连接。 2023-04-28 22:08:06.878 INFO [11036] D:\a\pulsar-client-cpp\pulsar-client-cpp\lib\ClientConnection:263 | [172.22.48.1:5376 -> 172.22.48.50:6650] Destroyed connection 2023-04-28 22:08:06.879 ERROR [11036] D:\a\pulsar-client-cpp\pulsar-client-cpp\lib\ClientConnection:616 | [172.22.48.1:5377 -> 172.22.48.50:6650] Read operation failed: 由本地系统中止网络连接。 2023-04-28 22:08:06.880 INFO [11036] D:\a\pulsar-client-cpp\pulsar-client-cpp\lib\ClientConnection:263 | [172.22.48.1:5377 -> 172.22.48.50:6650] Destroyed connection ``` The error message is `The network connection was aborted by the local system` in English.
