While working on one of the production issue I came across one error in oracle.
ORA-06508: PL/SQL: could not find program unit being called
When i checked in the database i can't found any invalid objects using below query.
select * from user_objects where status <> 'VALID';
Once all the packages are recompiled by me and then tried there was no error. This is occurring in Database from sometime. Did anyone faced any such issues in past.
Can you please help me finding the RCA for this issue.
