samba - Sep 2011 - Help needed to debug Samba problem

I have a Samba domain that is having problems.  We have a new NetApp file 
server (FAS2040 running NetApp Release 7.3.4) that keeps dropping its 
connection to the Samba server.  We didn't have this problem with an older 
NetApp box (FAS250 running NetApp Release 6.5.1R1).

I can run tcpdump on the Samba server and see traffic going back and forth 
between the FAS2040 and the Samba server when the filer tries to connect, 
but don't know enough about the protocol to decipher the traffic.

One thought I had was to move the Samba domain to a newer version of 
Samba (on a newer server) but I don't know if that will really help.

The above means that I have two questions:  how to decipher the tcpdump 
info, and how to migrate existing Samba tdb databases to a new server?

Thanks in advance for any pointers!

What does your setup look like ? How are you trying to export
files from what to what ?
