samba - Jan 2009 - Chronic Intermittent Problems with "File system does not support long filenames."

When trying to create a file or folder, or sometimes even rename a file,

on a samba share (3.0.28-0.el4.9) from a Windows 2003 R2 server, I 
occasionally receive an error message stating that the target filesystem

does not support long filenames. It does not always happen. Also, I have

another samba 3.0.28-0.el4.9 server where this does not happen at all.

What causes this?

Here's the smb.conf from the "bad" server. It's pretty much
the same as
the "good" server.
