Thanks for the reply, but I should have given more info...
running systat, I only get: "error reading kmem at c03db09c"
=2E.. And looking in dev:
lrwxrwxrwx  1 root  wheel  4 Jul 21 13:37 /dev/mem@ -> null
lrwxrwxrwx  1 root  wheel  4 Jul 21 13:37 /dev/kmem@ -> null

=46rom googling I understand this is a security restriction imposed by my j=
ails=20
provider.

I found a mention on freebsd-hackers archive of a patch to top:
http://www.mail-archive.com/freebsd-hackers@freebsd.org/msg33464.html
Does anyone use this patch + can recommend it?  If so, where can I get it?

I've also tried the perl module Sys::CpuLoad, but haven't found it very=20
usefule.

Any ideas/comments appreciated!
Thanks,
Cerion
