Thanks.  I thought I was just my two OS clients.  From what I've been 
reading lately, it seems to have been around for a while in different 
releases of OSX.  Our set up is one Samba PDC that acts as a file 
server for a bookkeeping business.  We have the mac machines as we 
have a couple of artist clients who do all their work on Macs, 
including their books.  We can't leave them connected to the network 
for too long or I have to restart samba.

I did an strace and logged it here - 

I am not sure what to look for though.  Maybe someone can shed some light...
