"Fetch out of Sequence" error message

A SQL*Plus script that has run perfectly every day for 2 years suddenly came back with ORA-01002. The official description is below:

ORA-01002 fetch out of sequence

Cause: In a host language program, a FETCH call was issued out of sequence. A successful parse-and-execute call must be issued before a fetch. This can occur if an attempt was made to FETCH from an active set after all records have been fetched. This may be caused by fetching from a SELECT FOR UPDATE cursor after a commit. A PL/SQL cursor loop implicitly does fetches and may also cause this error.

Action: Parse and execute a SQL statement before attempting to fetch the data.

Any ideas what might cause this or how to fix so that it can't happen again?
