Ursache
Ошибка PowerPath.
Во время бесперебойного обновления VPLEX через несколько секунд после возврата происходит сбой директора VPLEX. В результате в PowerPath была обнаружена ошибка, связанная с открытием устройства, из-за чего PowerPath выпускал дополнительный выпуск. Этот дополнительный выпуск приводит к состоянию использования памяти после освобождения памяти и критической ошибке ядра Linux.

Этот дополнительный выпуск приводит к состоянию использования памяти после освобождения памяти и критической ошибке ядра Linux.
Lösung
В PowerPath 6.1 HF1 и последующих выпусках PowerPath исправлена эта ошибка.
Weitere Informationen
И Red Hat, и PowerPath Engineering смогли воссоздать это состояние в лаборатории независимо от NDU VPLEX. Помимо обратной трассировки клиента, было обнаружено несколько различных обратных трассировок критической ошибки.
Из-за характера использования после освобождения памяти фактическая паника может наблюдаться в нескольких местах.
Обратная трассировка клиента #2
