Oracle ORA-03124 Two-task internal error

[Dan Davis]

Running my migrations with Django 1.11. (1.11.20), fails with the Oracle error ORA-03124 Two-task internal error.

I have tried this with Oracle instantclient 12.1.0.1 and 18.5.0.0., and several other versions of cx_Oracle.

There are no migrations to make, but I get the following error, always in the same place, the post_migrate handler for contentypes, after auth.

manage.py migrate -v 3
