The system used to run with untuned loader.conf, and my colleague just reported that with the following loader.conf, the problem can be triggered sooner: vm.kmem_size_max=838860800 vm.kmem_size_scale="2" The system is running FreeBSD/amd64 7.1-PRERELEASE equipped with 8GB of RAM with GENERIC kernel.
