Boy, ZFS sure does sound like it's earned the title of memory hog.  Oddly 
I'd been running for about a week without problems, and shuffled some 
large files around during that week, and right before I got your e-mail I 
had another hang.  I tried increasing the kmem_size setting and was 
rewarded with a panic on reboot.  I already had it set at 512M.  A little 
Googling tells me I'm going to have to compile a custom kernel to increase 
it beyond that.  Oh well, it's about time I learned how to do that anyway. 
I've compiled many a custom Linux kernel.  I started using Linux in the 
1.xx kernel days before there were loadable kernel modules so almost 
everything involved a kernel recompile.  I've read over the FreeBSD kernel 
compile docs quite a while back but will need to go over them again. 
Anyway, thanks for the tip.  I'll give it a try after a little research 
and a little, or a lot of, compiling.
