Cause

Kontroller igen hukommelsesstørrelsen, som den brugte CPU understøttes.

Den anvendte CPU er en Xeon Gold 5218 X2.
En enkelt CPU understøtter en hukommelsesstørrelse på 1 TB.

Under denne konfiguration kan 2 CPU'er understøtte op til 2 TB hukommelse.

Serverens hukommelseskapacitet har overskredet CPU'ens supportområde.

Resolution

Reducer hukommelseskapaciteten til 2 TB.

Monter hukommelsen i henhold til retningslinjerne for systemhukommelsen i installations- og servicemanualen.
