I got this last night:

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x800010
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xe0121320
stack pointer           = 0x10:0xdfbfff18
frame pointer           = 0x10:0xdfbfff28
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 7539 (named-xfer)
interrupt mask          = net tty 
panic: page fault

Can anyone tell me what it means?

The machine is a FreeBSD-2-2-stable with 384MB of RAM, with 3 patches from
DG and

      sysctl -w vm.v_free_reserved=1024
      sysctl -w vm.v_free_min=1500

in it's /etc/rc.local. It waas running named at the time, acting a a gTLD
nameserver (providing secondary service for .com, .net, .edu, etc zones). 
The named process runs to about 240MB.
