I might be willing to try to duplicate these crashes again, but for now I'm just happy the machine has mostly stabilized. I'm guessing I was just running into a resource exhaustion scenario with 4BSD and the panics I was running into with the 5.3-RELEASE GENERIC kernel were related to other problems which were fixed in the RELENG_5 branch. The RAID is currently rebuilding (I had to use a hacked twe driver to use the 32-bit 3Ware CLI on amd64) so I'd want to wait for that to finish, at least. Tony Arcieri
