samba - Sep 2010 - samba slow and several "Write andx Request"

Hi all,
I'm running version 3.0.28a on Ubuntu linux, and apparently from a day to 
another I got performance issues: without any change in smb.conf (except a few 
added shares) I have mac osx and linux clients getting a very slow 
upload/download speed. I've checked with other protocols, like scp and 
performances are good, so I can exclude a network/hardware problem.
Other clients are still running fast (e.g., windows xp). Looking at a 
transmission dump I see a lot of "Write Andx Request" packages (and
replies)
all moving the data offset by 64 bytes, that I suspect is the cause for the 
slowing down speed. Is there some option or somehting I can investigate more?

Thanks,
Luca

That's a really old version of Samba to be running on Ubuntu seems like you
might be running also a very old version of ubuntu itself.
Ubuntu 9.10 was running 3.4.0 as I recall and 10.04 is on 3.4.7 3.0.28 is
not even recommended for windows 7
http://wiki.samba.org/index.php/Windows7
so you will soon hit that wall as well.
Perhaps the issues you are having are fixed in later releases?
