[Samba] strange kind of sharing violation disappearing with socket options

[Philippe Strauss]

Hello,

On a samba (3.0.22 from samba.org on FC4) setup running at
one of our customer site, we got a strange kind of bogus sharing
violation using
excel and word (french version).

the messages, translated in english:

Excel:

"saving of the document has succeeded, but Excel was not able to
reopen-it due to
a sharing violation. Close the document and try to reopen-it".

"New sheet.xls is locked for modification by "Microsoft Corporation".
Open the document using the read-only option or click on Notify to open
a read-only copy of the document and get notified when the document
will be available".

Word:

"Unable to save: insufficiant memory or disk space".

small screenshots attached.

Now the strange thing is that those bogus behavior have ceased after
putting the following socket options in smb.conf:

TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

Anyone has an explanation?

here is the smb.conf:

[global]
