Hi all,We've experienced a recent kernel crash on a captive portal server running debian/wheezy with a standard kernel 3.2.0-4. The crash seems to be related to ipset that we're using to check bitmaps {ip,mac}. It has not been seen before on this production server.
Thanks for your help, Regards, -- Université de Nantes - Direction des Systèmes d'Information IM jabber: yoann.juet@xxxxxxxxxxxxxx Tél: 02.53.48.49.26 - Fax: 02.53.48.49.09
