samba - Sep 2009 - Samba Panic when attempting to connect using OS X client (3.3.7)

Hi,

Am running Samba 3.3.7 on FreeBSD 7.1. All Windows clients (W2K & WXP) can
connect fine but cannot connect any OS X clients (version 10.4 & 10.5).
These OS X client receive an error message saying it cannot connect. The log
indicates the following:

The contents of smb.conf is as follows:

        valid users = "@DSP-domain admins"

        directory mask = 0774

I've googled around for a possible fix to this but to no avail. I turned up
logging by setting up an individual smb.conf file for this particular OS X
client but am unsure if all relevant details are being logged. The log
states INTERNAL ERROR and according to the How-To PDF, it indicates a bug.
That so?

Reverting back to Samba 3.0.36 allows OS X clients to connect.

Let me know if additional details are needed.
