Hi, I get this issue sometimes after I tried to optimize the runtime of dags.
The parameters (and the default values) I modified in airflow.cfg include:
dagbag_import_timeout = 120 (30)
sql_alchemy_pool_size = 16 (8)
executor = LocalExecutor (SequentialExecutor)
Does anyone know what might cause this issue?
Thanks,
