Nanobsd fatal trap 12

[Guest]

So after a while of 3 days of operation, my nanobsd pfsense build kernel panic'd. Pfsense 2.03 amd64 nanobsd 2g

I am using the 2gig build with a 4gb sandisk cruzer.
Disk usage says 22% after the reboot.

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id =00
fault virtual address = 0x37e
fault code = supervisor read data, page not present
instruction pointer = 0x20:0xffffffff8060fadf
stack pointer =  0x20:0xffffffff003d7b5b30
frame pointer = 0x20:0xffffffff003d7b5bf0

code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1

processor eflags = interrupt enabled, resume, IOPL = 0

current process = 56573 (nice)
trap nuimer = 12
panic: page fault
cpuid = 0
Uptime: 3d16h15m29s

Any idea what this could mean?
