[Samba] All users getting brief disconnet?

[Deas, Jim]

I have a system that appears to reset several smb client every few days. I suspect a possible client dirty disconnect as the prime suspect. Can someone please look at this trace and tell me if I am on the right track? There are no smbd message within a day of this event leading up to the fault.
The system does recover itself but at the expense of all clients (Mac OSX) having to re-cache their files.
