Problem is that happens after ~50gb data already transfered and always
found it in "hang" state after time. I can check netstat and similar. I
can also try to fetch all packets between hosts .. that could also be
interesting? Thats a lot of data.

I will try to do as you wrote there..

Ok.. I have same problems with reading data from XP professional..
connections also hang. I'll try to do tests on both of samba 3.0.7 and
3.0.9 and XP (2003 or w2k can also do). First plan is testing on samba and
xp.
