Собрал livecd на базе CentOs7. Собирал при помощи livecd-create. В какой-то момент при записи файлов на рам диск возникает следующая ошибка: Dec  7 04:06:57 localhost kernel: device-mapper: snapshots: Invalidating snapshot: Unable to allocate exception.

При этом ни переполнения памяти, ни переполнения рамдиска не наблюдается - везде есть свободное место.
Грешил на битую память, но проблема повторяется на разных машинах, на которых памяти 4 гига и больше. На 2  гб проблемы нет.
Куда копать?
