Altro crash proprio ora. In realta' non si e' bloccato tutto subito: mi sono
tenuto una console di root aperta e un sistema per essere avvertito al volo
(ok, questa e' un po' lunga da spiegare) e ho provato immediatamente a lanciare
un reboot remoto (l'altra volta ho avuto qualche secondo e ho lanciato dmesg
ma il sistema si e' bloccato definitivamente, quindi stavolta ho provato solo
il 'reboot'). Comunque niente da fare, pure il reboot si e' bloccato ad un
qualche
punto. Questo il (lungo) log di stavolta:

-----------------------------------------------------------------------------------------------------------------
Alcune note interessanti. Per stressare il sistema (visto che al momento
_voglio_
capire il problema) ieri sera avevo lanciato l'upload di tre ISO da 700 Mb verso
un'altro server, raggiungibile su internet al 30Kb/sec (circa 20 ore di upload).
Avevo notato da tempo che i crash erano in concomitanza di carichi di rete
maggiori
della norma e infatti oggi, a a circa due terzi dell'upload e' successo il
crash.
Al momento avevo anche alcuni ssh sul PC in questione con poco traffico.
Come appare dai log, il processo che e' morto e' rsync (che ho usato per fare
l'upoload descritto prima).
Provo a cambiare kernel. Che mi suggerite? Al momento e' 2.6.17-2-vserver-k7
e potrei tornare a un 2.6.17-2-386. Non vedo altre versioni di linux-image-*
sulla debian testing...
