Where is your swap partition?

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.=20

Maybe something like the following to /boot/loader.conf may help... (or =
not)

vfs.zfs.arc_max=3D"2G"
