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? -- Dan Nelson dnelson@allantgroup.com
