PFSense 2.1.5 issues on Dell Server

[m4st3rc1p0]

fault code = supervisor read data, page not present
instruction pointer = 0x20:0xffffffff8023be83
stack pointer         = 0x28:0xffffff803ac145a0
frame pointer         = 0x28:0xffffff803ac145d0
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1

This is the error i normally recieved when I save info on squid filter and the hardware reset.

Have you run a memtest to qualify the memory?  Looks like that's only a partial fault message, do you have the rest?
