We are in the process of doing something similar (on a bit larger scale - roughly 500 servers and 12,000 windows clients) and had run into a similar experience. In working with some of the current Samba developers (as you know we (Novell) recently hired Jeremy Allison) have made many improvements to Samba 3 (current stable is 3.0.14a) that fixes some issues related to this - I don't know exactly what was fixed and exactly what the issues are, but you may wish to check for updates to your distro's code. Most likely the fixes for the high cpu loads and/or SMB_ASSERT will help tremendously.
