Serhii commented on AIRFLOW-1060:
---------------------------------

I have the same issue. It is 100% reproducible on 17.1.2 and 1.7.1.3 versions. If task takes more 1 hour then subdag containing this task stucks in running state.

In logs for SubDagOperator I have found some mysterious error:
 
[2017-04-04 15:04:35,076] {jobs.py:965} ERROR - The airflow run command failed at reporting an error. This should not occur in normal circumstances. Task state is 'running',reported state is 'success'. TI is <TaskInstance: socrates_migration_etl.preparations.topoReports_prepare 2017-04-04 14:00:16.677858 [running]>

> I'm running an airflow 1.7.1 in one of my environment and constantly run into an issue with the main dag status stuck in "running" state, while the tasks all have completed successfully.
> To resolve the issue, I had to "delete" the dag entry in airflow UI, and re-run the job manually so the dag job can recognize the tasks are all completed and set it self to successful after re-run.
