Isolation level 0 (no shared locks) has been configured for the database instance.
You have executed an SQL statement that references a nonexistent table or a nonexistent index. The table or index was deleted by another database user while you were executing your SQL statement.
The database system therefore terminated the execution of your SQL statement.
Assess whether isolation level 0 is appropriate for your database application.
