Crashes on sparc 10 running 2.7

[Brett Longworth <brettl_(_at_)_bio_(_dot_)_umass_(_dot_)_edu>]

Hi,

I'm getting (seemingly) random crashes about once a day on a Sparc 10 
with OpenBSD 2.7 installed.  It doesn't drop to the debugger, and leaves 
no panic messages that I've found.  Symptoms are usually not waking up 
from console screenblank, no response to ssh, nfs or pings.  It had 
crashed a twice under 2.5 which among other things prompted me to 
upgrade.  2.6 wouldn't work because of a bug when running on a SM30.

I'm thinking possibly bad memory.  Testing memory from the boot prompt 
produces no errors, but also doesn't spin through the memory being tested 
on screen as I'd expect.  Any ideas?  Diagnostics?  Ways to at least 
produce a corefile?

TIA
-Brett
