python - Airflow Dag Statuses Inconsistent in Webserver -


i have airflow cluster up, configured use celeryexecutor , postgres backend.

for reason, statuses of dags on webserver ui inconsistent every time refresh. upon each refresh, shows many different things such dag not available in webserver dagbag object, or black statuses, or hiding links on right.

it changes on each refresh.

here few screenshots:

run airflow web-server in debug mode can resolved

airflow webserver -p <<port>> -d

the problem seems dynamic code changes happening on new dag creation , hence production mode flask server not patching through
