Problème config serveur. Crash.

**niconeo** · 02/04/2008, 11h04

Bonjour,

Je pense avoir un problème de configuration sur ma machine qui me la fait tombé, mais je ne sais pas du tout d'ou cela peux venir j'ai cependant 2 pistes que je peux vous proposer pour m'aider

.

La première:

- J'ai programmé 1 cron qui tourne toutes les 15 minutes et peux renvoyer entre 10 et 50 lignes de donnée qui sont généralement envoyé par mail au root... Pour évité cela j'ai rajouté dans mes cron en fin de commande "MA COMMANDE >/dev/null 2>&1" afin de ne plus recevoir de mail...

Pensez-vous que ce problème pourrais être lié à celui-ci trouvé sur comment ca marche :

et surtout comment cela peux ce produire et ce corriger ?

La seconde:

J'ai analyser les logs mais je ne sais pas si le problème scsi est lié au problème d'écriture ou si c'est lui qui en est la cause...
