nfs_getpages: error 70

[Eugene Grosbein]

Hi!

What do these errors mean?

Mar 31 17:00:11 www /kernel: nfs_getpages: error 70
Mar 31 17:00:11 www /kernel: vm_fault: pager read error, pid 33624 (httpd)

I have Apache 1.3 server running on 4.9-STABLE. It processes requests to
plain html files located on mounted NFS filesystem.

NFS server is pre-PAE FreeBSD 4.8-STABLE system (plus security patches).
It often updates it file in this way:

make_new_version index.html.0
mv index.html.0 index.html

HTTP-clients refresh this file very often and sometimes they get the file,
but sometimes then get standard Apache 'Forbidden' error page.

Apache error log contains:
[error] [client x.x.x.x] (70)Stale NFS file handle: file
permissions deny server access: /mnt/main/netstat/index.html

What should I do to avoid this error?
