I haven't seen anything like this. All the 3100 RAM I have is in a
KMIN right now.  But if you had a kernel with DDB, you could type a
break to the serial console, get a DDB prompt, and do an in-kernel ps
to figure out if this was a kernel problem (e.g., out of physical
memory) or something else.

Should I add

	options		DDB
	options		DDB_ONPANIC=0

to the GENERIC kernel? That would mean DDB is present, and you can get
into it via the console, but the kernel won't enter it on a panic,
which makes rebooting remote machines without console access a fun
challenge.
