Bonjour !

Depuis quelques temps (depuis que j'ai changé le ventirad de mon serveur), ce dernier décide de redémarrer une fois de temps en temps sans motif valable (j'ai vérifié les températures et le processeur reste en dessous de 60C).

Il sert principalement pour du Plex donc c'est assez génant lorsqu'il se coupe au milieu d'un film.

Le serveur s'est ici redémarré à 21h 34.
Si vous avez besoins de quoi que ce soit dîtes moi.

Merci d'avance !

Ci joint le /var/log/syslog au moment du redémarrage :

Il n'y a pas de note dans le log que le systeme a ete redemarre d'une facon note par le log. Et le quand le systeme redemarre, ca genere un fsck qui indique que le systeme de fichier n'a pas ete unmounted correctement.

Je regarderai si le probleme est electrique. ca pourrait aussi etre un kernel panic tellement violent que ca ne genere pas de log. mais c'est peu provable. Je ferais tourne un memtest just pour voir quand meme.

depuis que j'ai changé le ventirad de mon serveur

C'est du pifomètre couplé à une analyse basique mais, as-tu gardé l'ancien ventirad ? Qu'est-ce qui se passe si tu remets l'ancien, justement ?

Bon dés que je lance un memtest le serveur redémarre je pense que je vais tester toutes les barrettes pour voir le problème.

Merci !
