My apologies if this is a repeat... I had some mail problems and I'm not
sure if this actually made it out or not.

Subject: Crash problem
Greetings once again,
A friend of mine is having some difficulty with his FreeBSD system. He's
currently running 2.2.2-RELEASE (I know we should upgrade, which we're
trying to do, but the problem we're experiencing is preventing that from
happening). The problem is that the machine would spontaneously reboot
without warning. He and another friend of his finally got some remote
logging set up, and this is what they found the last time it rebooted:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xd
fault code = supervisor write, page not present
instruction pointer = 0x8:0xf0129e32
stack pointer = 0x10:0xefbffdfc
frame pointer = 0x10:0xefbffe04
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 25263 (make)
interrupt mask = bio
panic: page fault

giving up
Automatic reboot in 15 seconds - press a key on the console to abort
Rebooting...
In this particular instance, it rebooted during the "make buildworld"
process. However, it doesn't seem to make a different what process is
running at the time. At first we thought it was memory, but we swapped
out the memory (it has 128 MB) and it still had problems. Then we became
suspicious of the swap drive, thinking perhaps it had a bad spot on it
somewhere. However, on the last crash, he was monitoring it, and it
hadn't even dipped into swap yet (at least it hadn't appeared to... maybe
it did and that's what caused the reboot... don't know).
We've noticed before that in, say, compiling a kernel, it will almost
invariably fail the first time (but won't crash the machine). Then, if
you do "make" again on the kernel, it'll pick up where it left off and
finish successfully. Obviously, I don't like seeing that, because that
tells me something is definitely wrong. Given the output above, does
anyone have any theories as to what the problem might be?
Thanks in advance,
Bryce
