-25313: Overflow occurred, execution aborted 

Explanation:

Error executing the Loader command for exporting data. A numerical value that is to be exported cannot be exported into the external format specified in the command. This error occurs if for instance you try to export the value 2147483647 from data type INTEGER into an external binary INTEGER value that is only 2 bytes long. When this error occurs you will only see an error message. Instead of numerical data, the data stream will only contain a corresponding number of asterisks (*). This error does not interrupt the data export.

User Response:

Check the data once it has been exported.
