With optimal, the rollback segment shrinks back to its optimal size as soon as the update, insert, or delete transaction is committed. However, there may be a long running query that is using that rollback segment for a consistent view of the database. If the rollback segment shrinks, the query cannot find the data that it needs. This results in a snapshot too old error.
