Ну и как водится, памагииииииите. Реально я думал, что это баг zfs (появилось после включения в ядре данной опции и переноса /usr туда. Когда был только /var (raidz на трех дисках), все было нормально), но после обновления ядра и мира это не прошло. То есть ядро я обновлял не только из-за этого, но все же это не помогло. Сам —очень сильно грешу на vm.kmem_size и некоторые другие параметры, которые пришлось менять при “ZFS-тюнинге”. В общем, чаще всего сервер умирает при нагрузках на ФС, что говорит о том, что кому-то (ядру или ZFS в ущерб друг друга) не хватает памяти.
