Which module? I am almost certain that your kernel is not trying to use 320+ MB of=20 RAM on a machine with 128 MB of physical memory available, so it is=20 likely that you are misunderstanding something. When you run top, the=20= size of the kernel is best reflected by the "wired" category. Speaking of which, what does top or "vmstat -s" say? > And, if i have to get more memory... how much more should i get? Would > 256MB be enough, or does FreeBSD 5.3 only run on 2GB+ machines now? What tasks are you running on the machine? FreeBSD will quite happily=20= work as a mail server, router, firewall, stuff like that in 128MB, but=20= if you are running X11 and a bunch of graphical apps, more RAM would=20 certainly help. [ If you avoid running a dozen or so virus scanner/antispam perl=20 thingies like SpamAssassin or amavisd with 30MB RSS each, you can run a=20= lightweight mail server fine in 32MB, although FreeBSD 4.x or NetBSD=20 would be better suited for a low-memory environment than FreeBSD 5.x=20 is... ] --=20 -Chuck
