There appear to be 2 leaked semaphore objects to clean up at shutdown

[Benedikt Buchert]

Hi,

All my dags are running just fine but my logs are bing flooded with this message:

{
  "textPayload": "/opt/python3.11/lib/python3.11/multiprocessing/resource_tracker.py:254: UserWarning: resource_tracker: There appear to be 2 leaked semaphore objects to clean up at shutdown",
  "insertId": "someid",
  "resource": {
    "type": "cloud_composer_environment",
    "labels": {
      "location": "europe-west3",
      "project_id": "myproject",
      "environment_name": "myenv"
    }
  },
  "timestamp": "2025-10-08T12:13:10.954170437Z",
  "severity": "WARNING",
  "labels": {

  "logName": "projects/myproject/logs/airflow-worker",
  "receiveTimestamp": "2025-10-08T12:13:17.650866942Z"
}

How can I debug the issue. And what is causing it?

Best Benedikt
