Сервер перезагружается случайным образом в разное время с интервалом в один день
У меня проблема. Я не знаю, в чем причина перезагрузки моего выделенного сервера. Хостинг-провайдер говорит, что с оборудованием все в порядке, и я сам должен найти причину в своем программном обеспечении. Мои логи из journalctl:

В чем может быть причина этих перезагрузок? Я ищу причину две недели. Это происходит с интервалом в один день, но иногда сервер может работать 3 дня без случайной перезагрузки. Очень-очень странно Пожалуйста, помогите, я не знаю, что мне делать. Софт на этом сервере:
os: ubuntu 18.04
kvm
lxd + zfs
Средняя нагрузка не более, чем 0.8, я имею 6 cores из CPU AMD Opteron(tm) Processor 4334 а также 32 Gb памяти.
