I knew someone would comment this. ;-)  Maybe I can find the courage to try
log with the 4.7 TB partition I have.  I'm just afraid of problems with
partitions as large as this.

I "upgraded" my 4.0 server to netbsd-5 by extracting the tarballs over
the old binaries, so old libraries and stuff were not deleted.  Maybe this
is causing me problems.. is it possible that the new nfsd is using libs
from NetBSD 4.0 and this is causing problems?
