My guess is you are hitting swap because you need to tune vfs.zfs.arc_max to allow room for the OS and any running applications. If you do not set arc_max then ZFS will basically consume all RAM save for about 1GB for the OS and any apps. Maybe something like the following to /boot/loader.conf may help... (or not) vfs.zfs.arc_max="2G" -- Robert inoc.net!rblayzor http://inoc.net/
