BTW, you should probably try 1.4.3 first.

When file is removed and it's ffs inode is re-used to hold information
about new file, the generation number increases so that it's possible
to find out it's not the same file.
IIRC vnode has also generation number for similar reasons, but
that's not probably of great importance to you.

ESTALE means either that the file was removed on server
(or by other client) and the reference a client holds is
no longer valid. Nothing to worry about too much, it's quite
normal.
