whole system

I still have my entries in /etc/system for
limiting
how much RAM zfs can use.
Going on 10 hours now, still importing. Still at just
under 2MB/S read speed on each disk in the pool.
And it's now froze again. Been frozen for 10 minutes now.
I had iostat working on the console, At the time of the freeze, it started
writing to the zfs pool disks, previous to that, it has been all reads.
The console cursor is still blinking at least, so it's not a hard lock. I'm
just gonna let it sit for a while and see what happens.
