Writing a large file through SLES 9 NFS client, fails after SLES 9 kernel 2.6.5-7.287

Environment

Novell SUSE Linux Enterprise Server 9 Support Pack 3
Novell SUSE Linux Enterprise Server 9 Support Pack 4

Situation

A SLES 9 client is downloading a file through one protocol (such as FTP), into a directory which is actually an NFS client mount.  So the file is then being written over the NFS protocol to a third system.  If the NFS client mount is using the 'intr' option, then the NFS writes could fail.  Depending on the FTP server, the FTP session may give an error code in the 400 range (often 426 or 451) such as:
 
426 Failure writing network stream
or
451 Generic File System Error
 
The NFS client layer may give an error to the FTP client layer, resulting in an error such as:
ftp: short write

Resolution

One of the NFS client fixes in the 2.6.5-7.287 kernel had a flaw which caused this problem. It has been corrected is available in kernel 2.6.5-7.312.
 
Short of that, one workaround is to remove the 'intr' option from the NFS mount configuration.
