[Pdns-users] Unexpected unanswered query when overload-queue-length is hit

I am using overload-queue-length to mitigate random sub domain attacks on PowerDNS Authoritative Server. 

Does this mean that the time an attack can be survived is limited to cache-ttl? Or do stale items from the packet cache remain being used for answers while overload-queue-length is applicable?
