Данные Aerospike исчезли

после добавления большого количества данных в мою базу данных aerospike многие данные исчезают. Я также пытался отключить TTL и выселение. Но ничего не сработало. В настоящее время я использую конфигурацию по умолчанию.

namespace test {
    replication-factor 2
    memory-size 4G
    default-ttl 30d # 30 days, use 0 to never expire/evict.
    storage-engine memory
}

сохранено 256 408 объектов (использование памяти 24%), через несколько минут осталось только 133 294 объекта (использование памяти 13%). Срок действия 13 229 объектов истек (кажется, правильно) 0 объектов удалено

Что случилось с моими данными?
