[jira] [Created] (AIRFLOW-99) Scheduler bug causing dead-lock

Hila Visan created AIRFLOW-99:
---------------------------------

             Summary: Scheduler bug causing dead-lock
                 Key: AIRFLOW-99
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-99
             Project: Apache Airflow
          Issue Type: Bug
          Components: scheduler
    Affects Versions: Airflow 1.7.0
         Environment: CentOS6.5, Airflow1.7, CeleryExecutor
            Reporter: Hila Visan


I have 2 DAGs - hourly DAG and Daily DAG.
The Daily DAG depends on the hourly (using ExternalTaskSensor).
The Daily DAG instances consume all the resources, and all of them are in "running" state -  waiting for the hourly DAG to be executed.

DAG that wait for something to happen should move to the waiting queue.
