:Well, that had not occured till 4.6-PRERELEASE.
:How can that be avoided?
:
:> The file in question appears to be /mnt/main/netstat/index.html.
:
:Exactly.
:
:> So the question is: Are you modifying, copying, overwriting, or
:> deleting this file on a different nfs client or on the server?
:
:NFS server updates this file often.

:Eugene Grosbein
You can try two things. First, try this:
update the file as index.html.new
mv index.html.new index.html
If that doesn't work then you may have to do it non-atomically and keep
the last file around so any open file descriptors and mmap()ings on the
client remain valid.
update the file as index.html.new
mv index.html index.html.old
mv index.html.new index.html
