[LUGOS] 0-order allocation failed

[Nejc Skoberne]

Zdravo.

Gre za enega ProLianta, 2 x Xeon 3GHz, 1GB RAM, hardverski RAID (Compaq Computer Corporation
Smart Array 64xx), Slackware 10.1, custom jedro 2.4.30. Dobra dva meseca je deloval
brezhibno, sedaj pa se je že drugič zapored sesul (popolnoma zmrznil - na nič se ni
odzival). V /var/log/messages je v času tik pred sesutjem obakrat nekaj takega (prvič
je bilo samo eno "0-order allocation failed" sporočilo):

Ima kdo kakšno idejo, kje naj začnem z raziskovanjem?

Hvala in LP,
