IG 3.6.1 DB Cleanup gives org.hibernate.exception.ConstraintViolationException: could not execute statement

Hi,

IG 3.6.1 using a postgresql database

I'f like to clean up the data (since the disk will  be running full eventually).

I have disabled achiving

When I choose to cleanup, the result is a failure with statement like:

org.hibernate.exception.ConstraintViolationException: could not execute statement

The catalina log says:

[ERROR] 2022-11-03 12:31:28 org.hibernate.engine.jdbc.spi.SqlExceptionHelper logExceptions - ERROR: update or delete on table "change_request_item" violates foreign key constraint "fk_ciav_item_id" on table "change_item_attr_value"
  Detail: Key (id)=(13) is still referenced from table "change_item_attr_value".

[SEVERE] 2022-11-03 12:31:28 com.netiq.iac.persistence.service.CleanupRunner run - [IG-SERVER] Encountered unexpected error: org.hibernate.exception.ConstraintViolationException: could not execute statement

Any ideas to what I can do about this?
