Can this problem slow my server ? not really, to cleanup, (re)configure your logger to ignore kernel messages, and you should be fine (if my assumption is actually correct) best, Herbert > Regards > > -- > Hervé Hénoch > Responsable informatique > Institut Sainte Catherine > 1750, chemin du Lavarin, 84000 Avignon > Téléphone : 04.90.27.57.44 > Messagerie : h.henoch@isc84.org >
