It seems to happen during the nightly/weekly scripts walking all over 
the disk with find(1), so there is definitely disk activity; that's
about as much disk activity as this box sees, since it mostly just
acts as sound system for my home office and the music storage in on
a NAS box currently and previously was on another NetBSD box (via
NFS in both cases).

No WAPBL on this system.. I never bothered since besides booting and
sysadmin tasks all the important data is elsewhere.  I do wonder if
the crashiness started around the time WAPBL was merged though; I'll
have to see if I can dig up some data and correlate it to what kernels
it was running at the time.
