Différent problème avec un serveur hébergé sur un VPS

[anou]

Bonjour,


J'ai 2 gros problèmes avec le petit serveur que j'héberge sur un VPS ( il est censé accueillir au grand maximum 16 joueurs en même temps )

Concernant les spécifications du VPS, les voici:
Processeur Intel Xeon L5520
4 vCore 2,4 GHz
64 Go SSD
4Go de Ram


Il n'y a aucun plugin sur le serveur, c'est un serveur Vanilla.


1er problème:

Parfois je peux voir sur la console des messages de ce style:

"[Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 4258ms behind, skipping 85 tick(s)"

La machine est bien réglée à la bonne heure alors je suppose que le serveur est surchargé mais je ne comprends pas pourquoi, car le processeur n'est pas utilisé a 100%, et l'utilisation de la RAM dépasse très rarement les 2Go sur les 4 disponibles.




Ensuite, autre problème, j'ai depuis Dimanche après midi eut carrément 3 crash du serveur avec comme rapport de crash ce qui suit:


Voici ci dessous un des 3 report de crash que nous avons pu avoir pour le moment.

Salut,

Pour les 1er problème on ne sait rien faire si ce n'est avoir un meilleur serveur
Problème 2, possible d'avoir tes logs ? Parfois c'est plus claire...


Cordialement,
Detobel36

 

[anou]

Voici le dernier fichier logs

http://pastebin.com/Mi1mt9bv

Merci.

 

[Detobel36]

Salut,

Voici le dernier fichier logs

Merci mais la ce sont les logs après le crach... Il me faudrait les logs au moment du crach (à savoir les logs du 19 octobre à 7h36 du matin...).
A première vue aucun problème sinon


Cordialement,
Detobel36

[07:33:28] [Server Watchdog/FATAL]: A single server tick took 71.66 seconds (should be max 0.05)

Le message est assez explicite: Un tick a duré une minute et onze secondes au lieu de cinq centièmes de seconde (maximum toléré).
Ton serveur a pas les couilles specs suffisantes pour tenir, généralement quand t'as ce genre d'erreurs c'est que c'est assez injouable.

Le processeur n'arrive pas à suivre. Un peu normal vu son age et sa faible fréquence : http://ark.intel.com/fr/products/40...or-L5520-8M-Cache-2_26-GHz-5_86-GTs-Intel-QPI

Comment ouvre tu le fichier jar du serveur ?
Sous quel système d'exploitation est le pc ?
Essaie d'ouvrir le serveur avec cette commande : java -Xms512M Xmx3G -jar [chemin du jar du serveur]

 

[anou]

Bonjour,

C'est sous linux debian 8 64bits.
AU niveau de l'ouverture du fichier jar, cela se fait automatiquement, j'ai suivi le tutoriel suivant pour installer mincraft sur la machine: https://www.nodilex.com/fr/communit...nilla-avec-sauvegarde-automatique-sur-debian/

Et j'utilise la commande suivante: "java -Xmx3072M -Xms1024M -jar serveur.jar nogui"
J'ai aussi essayé avec "java -Xmx4096M -Xms1536M -jar serveur.jar nogui"
Mais cela ne change rien.



L'utilisation du processeur: http://hpics.li/062cd09



@Astequ Oui j'aurais dis exactement la même chose, sauf que l'usage de la RAM n'est jamais poussé à son maximum ni l'utilisation du processeur.
J'ai cependant pu trouver sur internet des gens ayant le même problème, cela proviendrait de minecraft 1.8

https://bugs.mojang.com/browse/MC-63590


J'ai cependant déjà mis en paramètre de serveur l'option de tick time à -1 mais rien n'y fais, le problème est toujours présent.


Merci.

 

[123456789qwerty]

Essaie de mettre Minecraft serveur 1.7 pour voir si tu le même problème.
