You have far too much CPU power and really not enough RAM. Maybe somebody else could confirm this? By the way, what are the memory requirements for Samba 3.0? I remember having read somewhere it was something like 3-4 Mb per connexion, but this was with 2.2...My personnal opinion is that it seems that 3.0 requires more. bye, Fabien
