Je gère quelques serveurs pour les services de base (NTP, DNS, etc.) et je viens de penser qu'un des serveurs semble garder les 3 derniers noyaux, au lieu de 2 sur les autres:

Tous les serveurs sont maintenus à l'identique, je ne sais pas ce que j'aurais pu faire, doit être un paramètre quelque part mais ne le trouve pas!
Veuillez nourrir ma curiosité! Merci
