on a 4D/70 gt w/ 16 meg, which sits quiet for a day or so, we
get a kernel panic:

PANIC: Kernel Fault
PC: 0x80068808 'Read Address Error'
Bad Addr: 0x19
Cause: 0x300000010<CE1,CE0>
SR: 0xFF34<IM7,IM6,...,IM0,KUo,IEo,IEp>

has anyone seen this before?  what would be some likely suspects
(particular microcode, a rarely-woken but corrupt daemon, etc.)?

also, what can be done with the files written to /usr/adm/crash?
i tried cd'ing there, renaming vmcore.n to core, and running dbx
on the unix.n i found there.  but this doesn't seem right,
and in any case doesn't produce any noticeably useful effect.

thanks much for any help you can offer,
