After upgrade, errors such as the one below occur intermittently:

ORA-04065: not executed, altered or dropped stored procedure
"<procedure name>"
ORA-06508: PL/SQL: could not find program unit being called:
"<procedure name>"

The procedure name can be a dictionary object (DBMS_OUTPUT, DBMS_UTILITY are common examples) or a user created object.
Another possible symptom is the sudden object invalidation without an obvious cause.

DBA_REGISTRY shows all components as being valid.
The issue is not reproducible because of the intermittent nature of the error.


Known scenarios when such situations have occurred:
