OperationalError: disk I/O error

Any fix to this? Is the error related to Flask?

Start at the register entry point in core/user.py and follow the call into core/db.py, especially sentences_victim and sql_insert. Reproduce the /register POST and inspect why the commit reports a disk I/O error. Done means registration completes successfully without this exception and the affected database operation is verified.
