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.
