This is a custom message from an application, so for guaranteed results you need to consult with the person supporting the application. However, from the messages it appears that the COBOL program got a file status 23 (record not found) while doing a START on a key of all spaces.
I would start by checking to see if the file got deleted and redefined before the program ran, and possibly had a problem reloading the data. The fact that the program is aborting due to failure of a START on space says there's an expectation in the program of having the START succeed.
