Airflow received sigterm. terminating subprocesses

Scheduler Timeout

• The Airflow scheduler may have enforced a task timeout (e.g., due to exceeding the execution_timeout parameter) and sent SIGTERM to stop the task.

Manual Termination

• A user or system admin may have manually terminated the task using airflow tasks kill or similar commands.

Orphaned Process

• The PID mismatch suggests that the task may have been restarted or orphaned, causing Airflow to send SIGTERM to clean up inconsistent state.

Resource Constraints

• The system or container running Airflow might have terminated the process due to resource exhaustion (e.g., memory, CPU limits).

Upstream Dependency or DAG Conflict

• If the task was part of a larger workflow, another task or operator failure could trigger an early termination.
