Impact Analysis Issue


I am performing a Impact Analysis (OOTB call method) via customization workflow. In our environment we have around 1L + identities. When i do perform impact analysis with particular department or some few users, it executes fine. When I go with all the users, it gives a below error.

an unexpected error occurred: org.hibernate.exception.GenericJDBCException: Could not get next iterator result

Can anyone help me out or advise ?

I have the same problem.
