error 70 is 'stale NFS file handle', which means that the web server
running on the NFS client tried to access a page from a file that has
been ripped out from under it (probably by the NFS server itself since
client deletions usually use the NFS rename hack).
The only safe solution is to figure out what is deleting or overwriting
the file and make it rename the file to something else instead, then have
a cron job that goes in every so often and deletes the renamed files
over X amount of time old.
