Concurrent Jobs - The spark driver has stopped unexpectedly!

Hi, I am running concurrent notebooks in concurrent workflow jobs in job compute cluster c5a.8xlarge with 5-7 worker nodes. Each job has 100 concurrent child notebooks and there are 10 job instances. 8/10 jobs gives the error the spark driver has stopped unexpectedly and is restarting. Your notebook will be automatically reattached.

How can I resolve that?
