Miss34 Posté 5 Septembre 2005 Posté 5 Septembre 2005 Je me permets de poster sur le forum pour demander votre aide. En effet je cale depuis plusieurs semaines. Je me suis déjà renseigné sur plusieurs forums, mais sans succès. Peut être que sur celui ci, certaines personnes ont un serveur du même type et seraient aptes à apporter une piste. En fait, chaque matin, aux alentours de 10h30, le serveur rame beaucoup : cela se traduit par une charge qui passe brutalement de 5 / 10 (charge habituelle) à 50 / 60 / .. voire beaucoup plus (j'ai vu un 200 même...). Et cela dure jusqu'à environ 12h / 13h. Le serveur est un double Xeon avec 4 GO de RAM. - Le site n'a aucune fréquentation particuliere à ces heures ci. - Aucun fichier de log ne dépasse 2 GO et le disque n'est pas plein - Les logs apache sont désactivés - Aucune tache cron n'est datée à cette tranche horaire. - Un redémarrage de mysql ne résoud pas le problème. Les graphiques MPRTG montrent qu'il y a énormément d'accès disques à ces périodes là (MRTG : http://ns610.ovh.net/mrtg) La commande top montre que le système ne swappe pas. J'ai tenté de reinstaller MySQL > rien .. OPTIMIZE sur toutes les tables > rien (je pensais à ça, car j'utilise quelques tables d'environ 2 GO) J'ai soupsonné le module de cache PHP pour Apache (eaccelerator) : la réinstallation et même la désactvation ne change rien. J'ai finallement tenté un reboot du serveur : le problème ne change pas non plus ... J'ai donc songé à un aspirateur de site. En activant les logs sur une période de très fort ralentissement, je n'ai observé rien de spécial. Voilà le résultat d'un ps : PID TTY STAT TIME COMMAND 1 ? S 0:08 init [3] 2 ? SW 0:00 [keventd] 3 ?

Miss34 Posté 5 Septembre 2005 Auteur Posté 5 Septembre 2005 Ca ne vient pas d'apache. Le problème est une avanlanche de causes à effet : Plein d'acces disque (qui ne viennent pas d'apache à la base) => disque dur rame .. => requetes sql, et transferts de fichiers plus lents .... => requetes apache lentes ...... => plein de process simultanés
Miss34 Posté 8 Septembre 2005 Auteur Posté 8 Septembre 2005 Je viens de constater plusieurs trucs : Je remarque que pendant ces fortes charges, j'ai des processus en D dans mon ps. Et je remarque aussi en faisant un " lsof | wc -l " que j'ai 20 à 30 mille descripteurs de fichiers ouverts. Ca arrive d'un seul coup ... D'où ça pourrait venir ?
