O servidor Ubuntu é desligado automaticamente

Question

Meu servidor ubuntu (vserver) está sendo desligado automaticamente às vezes e não sei por quê.

syslog.log antes de desligar:

Eu não vi nada no syslog. Seria possível ver mais dos outros logs? Eu também desabilitaria o IPV6, simplesmente porque parece que o seu provedor não o oferece.
