So dumpdev won't work to collect crash data. You might set hw.physmem to a smaller value in loader.conf to fit within the amount of swapspace which is available: set hw.physmem= MAXMEM (i386 only) Limits the amount of physical memory space available to the system to bytes. may have a k, M or G suffix to indicate kilobytes, megabytes and gigabytes respectively. Note that the current i386 architecture limits this value to 4GB. > What I'm really in need of is some way to determine the cause of reboots, > and panic messages aren't being logged.

That's unforunate, hmm, you might try leaving an ssh session logged in doing a tail -f on /var/log/messages and see whether you can get anything from that.
