Bonjour,

dans /var/log/messages à chaque heure j'ai une suite de messages du type :

J'ai ce bloc de messages 5 fois (1 par minute) toutes les 5 premières minutes de chaque heure.
C'est un serveur Fedora 11 de chez OVH.
Aucun programme lancé par le cron ne provoque ces messages.

Quelqu'un aurait-il une idée ?
