GoDaddy Error – Stale NFS file handle

I’m the only one here who has this error?

Warning: require(/home/content/90/5962090/html/byrev_org/wp-includes/compat.php) [function.require]: failed to open stream: Stale NFS file handle in /home/content/90/5962090/html/byrev_org/wp-settings.php  on line 265

„Stale NFS file handle” !?

And error occurs on multiple sites in the same hosting account.

Another problem is multiple „404 Error” but when checking the FTP, the files are ok there.

„File Manager” from interface hosting account does not work !!!

Today, Is not the 1’st time!
