You've probably reduced kmem_size from the default. I don't set anything on
my 6 GB amd64 system, and I get:
$ sysctl vm.kmem_size vm.kmem_size_max
vm.kmem_size: 2061496320
vm.kmem_size_max: 3865468109
I assume your 16GB system would default to even larger numbers. What values
do you get without forcing anything in loader.conf?
