As per this suggestion I set this value to 2*8G: vm.kmem_size="17179869184" And bfore the kernel boots this value is set in the loader. Tested it by goinginto the loader and show the value. But once booted I still get: [/boot] wjw@zfs.digiware.nl> sysctl vm.kmem_size vm.kmem_size: 3718209536 So who is resetting this value??? Thanx, -WjW
