Беспричинная падение STACK MES2348P

[Ausha]

Добрый день,
Пару дней назад случилась неприятность с потерей сервисов обеспечиваемых коммутаторами на время около 3-4 минут. (Случилось это как назло во время онлайн совещания, что еще больше задело)
Линки обеспечивающие стекирование сами отключились и началось перестроение стека (перевыбор мастери и бэкап), на части портов пропало PoE.
Ниже информация из логов.

Физические порты через которые осуществляется стекирование не участвуют в передачи трафика, но почему все они Not conected? если они соединены?


После перестроения STACK собрался не правильно, 2й коммутатор стал мастери.

Кто то сталкивался с подобным поведением коммутаторов в STACK? Проблема очень острая.


После перезагрузки стека он собрался правильно
