reboot after panic : page fault for two consecutive days now with FreeBSD stable 7.0

This is on a relatively new Dell dualcore with 4G of ram running up to  
date stable.  I'm not on site so I have no idea what might be  
provoking these crashes.  In fact in many years of running FreeBSD  
I've not seen something just happen like this.  It is a  
simi-production machine that cvsups daily and builds and installs a  
new world and kernel.  Ports are updated about once a week and haven't  
seen any issues previously.  It has been running 24/7 since new, about  
8 months.

3 files were generated info, bounds and vmcore.  The info file follows:

Dump header from device /dev/mfid0s1b
   Architecture: i386
   Architecture Version: 2
   Dump Length: 341225472B (325 MB)
   Blocksize: 512
   Dumptime: Wed Jun 11 12:34:24 2008
   Magic: FreeBSD Kernel Dump
   Version String: FreeBSD 7.0-STABLE #258: Tue Jun 10 05:54:42 CDT 2008
     root at
   Panic String: page fault
   Dump Parity: 2395754794
   Bounds: 2
   Dump Status: good

the vmcore is about 300M so I'm not attaching it;) I could put it on  
line at a moments notice.  I think that what I need is probably a  
crash course on debugging a crash and I really don't know where to  
start since after over 10 years with freebsd I've never needed it.   
Any help, suggestions, etc. would be greatly appreciated.
