[Samba] SMBD Crash

Our software utilizes an OS X Server (Snow Leopard 10.6.8) for file
read and writes. We gather files out of many directories, process
them, and then write files back to the server.
We had a long time end user who utilizes our software with an XP box
upgrade from XP to Windows 7.
Now with Windows 7 the SMBD is crashing routinely under heavy loads.
Whatever information it was working on at the time is corrupted. EVEN
WORSE the SMBD respawns silently under a new process and reconnects,
so we don't know that the smb server crashed or that the data has
become corrupt.
The problem is intermitant, but frequent. I'll throw 16 duplicates of
the same file at the system and it will fail on, say, files 11 and
16. This is the same file under a different name.
Here's a sample crash log (they're all about the same.)

We turned up the logging on the SMB protocol, and found this around

----------------------
Now keep in mind that we've been authenticated as "rip" all along, it
just decided some 19,000,000 UNIX System calls (not an exageration)
into the process that it couldn't locate the user "rip."
We're desperate for a solution, but so far all the tweaks we've done
on both the smb.conf and the Windows 7 registry have come up empty.
Can anyone point us in the direction of a solution?
