I keep getting a Fatal Trap 12: page fault while in kernel mode.
Initially, it would happen approx. every 6 hours.  However, over the
past few days, it has occured more frequent.



here's the error.
------------------------------------------------------------------------------------------------------------

Fatal Trap 12: page fault while in kernel mode
fault virutal address = 0x8
fault code               = supervisor read, page not present
Instruction pointer   = 0x8:0xc018c788
Stack pointer          = 0x10:0xc028ae84
Frame pointer         = 0x10:0xc028ae8c
code segment         = base 0x0, limit 0xfffff, type 0x1b
                             = DPC 0, pres1, def32 1, gran 1
processor eflags     = interupt enabled, resume, IOPL = 0
Current Process     = Idle
Interupt mask         =
Tap #                    = 12
panic                     = page fault

it syncs the disk, states the uptime and then reboots.

system stats:
  Dell Dimension XPS P200i
  Pentium 200MHz
  32 Mb Ram
  2 GIG HDD


I read through the FreeBSD site,
http://www.freebsd.org/FAQ/hackers.html, section 13.13 - Making the most

of a kernel panic. I read the article and near the end, it stats that
the dump will be about the same site as physical memory (RAM).  Since I
have 32M of RAM, it would be rather large to attach.

I have heard that this issue may be related to bad hardware
configuration, but this issue started after I installed FreeBSD4 -stable

(clean).  I was previously running v3.2 and fuge'd er attempting to
upgrade via cvs ( obviously inexperienced user...hahaha!)

Could someone provide a little insite into this issue!

Thank you
