Problem with dynamic DAG creation

I am creating dynamic DAGs using Variables in Airflow.
One of my DAGs update the the variable and then trigger a DAG. The triggered DAG fetches the variable and create tasks out of it. The problem arises when that Variable is again while my triggered DAG is still running.
How can I solve this?

Hi @brihati; yeah this is a tough one, unfortunately no clear workarounds come to me off the top of my head.

Were you using the instructions here?

Can you prevent other users on your team from changing that variable?
