--- Comment #36 from Lexi Winter <lexi.freebsd@le-fay.org> ---
fwiw, my own issue with NFS+mmap() was using net-p2p/rtorrent, which is a
fairly widely used application and which (famously) uses mmap() for nearly =
all
filesystem operations.  when running it on NFS, i found it frequently repor=
ted
data corruption issues with the files it wrote to (i.e., it would write to
files using mmap(), but on reading those files later, the data that was wri=
tten
was not as expected).

that said, i am the only person (other than Geoffrey) who i've seen report
issues related to this.  i couldn't say whether this is because the number =
of
people who use FreeBSD NFS and mmap() is relatively small, or because the
problem was caused by something else.

i only mention this at all to add some context to the discussion :-)
