Hmm, I don't know enough to give you a confident answer yet. However, I recommend checking the [Airbyte documentation](https://docs.airbyte.com) and [Airbyte forum](https://discuss.airbyte.io) for similar issues and potential solutions.

Based on the provided extracts, it's not clear why the "on success close procedure" is being executed in your specific case. However, it's important to note that the "on success close procedure" is a normal part of the Airbyte data processing flow.

If you're experiencing any issues or need more information about Airbyte connectors or the Airbyte protocol, you can refer to the [Airbyte documentation](https://docs.airbyte.com/understanding-airbyte/airbyte-protocol).
