Fuite mémoire

Salut,

Mon serveur ne répondait plus aujourd'hui.

Dans /var/log/syslog je vois que c'est parce qu'il n'avait plus de RAM ni de swap.
Y'a-t-il un moyen de savoir, après reboot, quelle application a tout utilisé ?

Merci de votre aide.

Re : Fuite mémoire

Je ne pense pas. Par curiosité tu pourra nous copier le message présent dans /var/sys/log ?
