--- Comment #1 from Konstantin Belousov <kib@FreeBSD.org> ---
Do you mean that file on server is not updated after the client writes through
a mmapped region?  If yes, this is how it should work.  File is consistent on
client, but not on server/other clients. For inter-machine consistency, NFS
provides close-to-open consistency, but since you closed file earlier, that did
not acted.
