Hi Experts.

We have recently start evaluation of new Oracle Database version in Development and QA environment.

I have observed multiple errors as in database alerts log as below. These errors are reported for Oracle internal queries, not for application queries.

Please give your valuable suggestion or inputs for these errors.
