Like others, I'll also suggest adding at least a little swap. If you
don't have disk space outside of the ZFS pool (recommended way to
create a swap), you can create one inside, with a zvol :
zfs create -V 2G -o org.freebsd:swap=on -o primarycache=none -o
secondarycache=none -o tank/swap
I sometimes use "-b 8K" and "-o checksum=off" for the swap, but
haven't stress tested this under 9-CURRENT and ZFS v28.

Like others, I'll also *strongly* suggest fixing that ada5 problem.
Try to run smartctl on the disk to see the problem. If the disk is
bad, replace it ! Don't wait "for a few months" if you don't want to
definitely loose your data.
