La pubblicazione dell'aggiornamento 9.16.18 \u00e8 stata ritardata a causa dell'emergere di ulteriori due errori, che sono rimasti irrisolti nelle versioni 9.16.18 e 9.17.15. Gli errori causano un'interruzione reciproca durante l'inizializzazione e si manifestano in configurazioni in cui nelle politiche dnssec-policy vengono utilizzate zone identiche, presenti in diverse viste (view). Gli utenti con configurazioni simili sono invitati a tornare alla versione BIND 9.16.16.
