Cause

Zařízení PowerProtect používá k provádění některých interních funkcí databázi PostgreSQL. Došlo k problému s vyčerpáním paměti, protože příliš mnoho procesů Postgres běželo a zahltilo soubor /var/log/messages opakovanými položkami procesu jádra. V jednom případě zařízení PowerProtect využívalo 15 GB paměti 422 procesů Postgres. Podmínka Postgres způsobila, že soubor /var/log/messages spotřeboval zbývající místo na disku (příklad 11G) za ~14 hodin.
