Support Debian
#1

Bonjour,

J’ai installé une distrib Debian 2.6.18 qui fonctionne plutot bien. Mon pc (p4 256 de ram pour vous donner une idee) est un portable dediée a heberge un site web (php, mysql) ainsi que du vsftp.
Tout est mis en place, il a tourné toute la journée et, quand je suis rentré cette nuit, il avait planté.

Mon syslog juste avant le plantage :

Lorsque je fais un top apres un redemarrage (au bouton …) :

[quote]Tasks: 54 total, 1 running, 53 sleeping, 0 stopped, 0 zombie

La swap n’est pas utilisée apparemment (bien qu’elle soit montée et activée). Pensez vous que cela vienne de la, et que puis je faire ?

Merci

Salut,
Moi le swap est rarement utlisé à part quand je fais des jeux, je ne pense pas qu’il y ait un problème avec ton swap :slightly_smiling:

#3

Merci elwario pour ton aide.

J’ai allumé mon pc a midi, et je n’ai que le vsftp qui tourne (avec ssh et samba), je n’ai aucune interface graphique, rien de tout ca, mysql et apache sont arrété.
Ce que je ne comprends pas, c’est que 4h apres, voila ce que me donne un top :

La Ram est completement utilisé, et je sens bien qu’un bug comme hier ne vas pas tarder …

Merci

Essaye de reformetter ta partition swap:

par exemple

swapoff /dev/hda7

mkswap /dev/hda7

swapon /dev/hda7

#5

J’ai testé tes commandes fran.b, ca a l’air de un peu mieux fonctionner.

Je me suis rendu compte que c’etait apache et mysql qui me prenaient toutes les ressources, du coup, je les desactives a chaque demarrage en attendant de trouver une solution …

Merci pour vos reponses
