Briefly, this error occurs when Elasticsearch’s Machine Learning (ML) feature tries to delete expired data but encounters an issue, causing the deletion process to stop until the next scheduled deletion. This could be due to insufficient permissions, a full disk, or a network issue. To resolve this, ensure that the Elasticsearch process has the necessary permissions to delete data.
