pfSense Keeps Crashing

[ChrisMurph]

My pfSense setup keeps crashing. I submitted a report today as well as a few weeks ago. It's been happening every couple days now.
I'm not sure how to diagnose what is causing the crashing. My setup had been operational without crashing until now (years), which has been great!

Any help would be greatly appreciated!

Here is an excerpt from my syslog (looks like a page fault occurred):

Looks like faulty RAM for me ... IMHO
Maybe you can run a memtest at boot?
