A while ago, some problems were found (through Apple) in the NFS code,
a testprogram was floating around, and FreeBSD fixed the problems they
had. I ran the testprogram, noticed that NetBSD had one or two of
the same problems, and fixed them. The other problems reported on
FreeBSD were not present in our code, not that I could see and/or
reproduce. Your problem may not be related to these problems at all.

I'm not aware of any such problem; it's hard to tell what your problem
is. The error you see if a fairly high-level database error, you'll
need to uncover what actually goes wrong on a lower level.
