Comment:

Can you confirm if the issue affects the Django master branch with Oracle 12? Django 2.0 (the master branch) drops support for Oracle 11.2. Unless this is a regression from previous Django releases, we won't fix the issue in Django 1.11.

    5 Reason:
    6  Django does search_related with id__in of 100k different ids. Oracle (at least 11.2) cannot handle it and blows up. (This is known by Oracle IIRC but not fixed at least not in 11.)
