Здравствуйте! В работу недавно установлен коммутатор DGS-3130-54TS Rev. B1 с версией прошивки 2.00.B057. Во время работы происходит перезагрузка коммутатора в связи с крашем системной задачи, связанной с DNS (dnsRxTask). Cудя по информации из error-log, процесс пытается обратиться к памяти, которой не существует. Баг в прошивке?
