Hi.

I have:
NetBSD 5.0_STABLE (GENERIC.MP) #0: Fri Nov 27 10:40:10 CET 2009
        jkunz@MissSophie:/datengrab/src/NetBSD/release-5/objdir/sparc64/sys/arch
/sparc64/compile/GENERIC.MP
total memory = 1024 MB
avail memory = 992 MB
timecounter: Timecounters tick every 10.000 msec
mainbus0 (root): SUNW,Ultra-60 (Netra t 1120/1125): hostid 12345678

This machine crashes about once a week with:
NetBSD/sparc64 (Maja) (console)

Externally Initiated Reset
{2} ok 

The machine serves as a NFS and NIS server with nearly no load.
/ and /usr are on a pair of RAIDframe mirrored disks, /home is an
external hardware RAID5. Filesystems are mounted with option "log".

Software bug or broken hardware?
