[Samba] Files That Constantly Change

Does anybody have any tuning tips for a samba 3.0.23 server that is  
acting as a PDC with ldap backend and file server. The problem I'm  
having is a certain program runs in XP workstations that accesses  
files on one of the shares, it apparently opens lots of files and is  
constantly making changes to them. When I run top, I see each smbd  
process for each workstations is consuming about 30% of the cpu and  
there are 3 workstations, the owner for the processes is the domain  
user logged onto the workstation. I have the same setup at a  
different site running samba 3.0.10 with just a smbpasswd backend and  
each workstation consumes about 2% of the cpu at most. These are in  
the samba logs for the workstation and are constantly being output:
