Problème WordPress Crashing, nginx et fastcgi?

Question

J'ai actuellement ce problème avec mon site wordpress où il travaillera pendant environ un jour après un redémarrage du serveur, mais a frappé cette série d'erreurs:

2015/12/15 22:06:42 [crit] 12650#0: *28 connect() to unix:/var/run/php5-fpm.sock failed (2: No such file or directory) while connecting to upstream, client: 46.166.139.20, server: example.com, request: "POST /xmlrpc.php HTTP/1.0", $

Ensuite, le journal des erreurs répète simplement que (11: Code temporairement indisponible) code encore et encore. À ce stade, essayer d'accéder au site lui-même donne juste une page nginx "une erreur s'est produite", me disant de vérifier les journaux d'erreurs.

Je ne sais pas exactement ce qui provoque le hold-up initial, et il semble qu'après quelques temps d'arrêt, le serveur se bloque complètement. Aucun conseil? Merci!

Quelqu'un de 46.166.139.20 essaie de deviner votre mot de passe. Si vous n'utilisez pas XML-RPC de WP, vous devez le désactiver.
