[Tech] Strani messaggi dal kernel

[Marco A. Calamari]

Stamani trovo la mia Soekris impallata.
Rispomde solo sulla console, illogin fnziona e trovo solo questi
processi

  PID TTY      STAT   TIME COMMAND
    1 ?        S      0:04 init [2]
    2 ?        SN     0:00 [ksoftirqd/0]

Il log dice

Nessun messaggio di log posteriore e dal'uptime la macchina
 non ha ribootstrappato, ma e' irraggiungibile via rete.
Ha solo 64 Mb ram e niente swap.
Un collasso da memoria esaurita ? Ma non dovrebbe solo
 impedire a processi nuovi di partire ?

Grazie a tutti.   Marco
