Hey folks,
I've had a helluva week - my colocated server has crashed at least
four times, and I'd like a little sanity check from people that know
a lot more than I do. Sorry for the length of this, trying to include
all the data I'm aware of that might be relevant and helpful.
For the two crashes that I've been able to capture some output
from (one from an IP KVM, one from /var/log/messages after setting
ddb.panic=0), I've seen:
uvm_fault(0xffffffff81cf2b20, 0xffff800000cef000, 0, 2) -> e
kernel: page fault trap, code=0
Stopped at memmove+0x16: repe movsq (%rsi),%es:(%rdi)
and
reboot after panic: trap type 8, code=0, pc=ffffffff81292dff
Because kernel panics are so rare in OpenBSD, I don't have much
experience debugging them. Following crash(8), I fired up gdb and
took a look at this morning's crash and auto-reboot:

I don't *think* it was resource starvation:

The reason I am suspecting hardware is because I have run -CURRENT
snapshots on this system forever, and this is suddenly rearing its
ugly head. I was running a snapshot from February when it crashed the
first time a week from yesterday, so I went ahead and updated to
"OpenBSD 5.4-current (GENERIC.MP) #54: Tue Sep 10 17:21:35 MDT 2013".
It has since crashed another three times, which is why I doubt it's a
software issue.
Could someone that has some more knowledge about kernel panics take
a look and make a suggestion if possible? Would you suspect RAM? CPU?
Some other hardware bit? I didn't really see anything obvious to a
kernel novice other than 'memmove', so I would appreciate any and all
help you could give me to help track this down (and perhaps point the
hosting company towards a failing component if that's what it turns out
to be).
And the dmesg:
