The problem there is, that user/group rules are basically a layering violation and thus cause a LOR which might lead to a deadlock. We are working on a fix for that, but it might be a couple of weeks before that happens. Please do away with the user/group rules for now or enable Giant over the netstack. -- /"\ Best regards, | mlaier@freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mlaier@EFnet / \ ASCII Ribbon Campaign | Against HTML Mail and News
