[Samba] copying large number of files from XP to Samba fails

I have a new Sun Fire AMD64 server running Solaris 10 12/06 and Samba  
3.0.21b.  I have migrated a configuration file from an older RHEL  
machine running Samba 2.2.x.  On this new machine, if one tries to  
copy a large number of files from a Windows XP client to the server,  
the copy starts and runs for a few minutes, but then stops.  The  
error message on the XP machine is "Cannot copy [filename]: The  
specified network name is no longer available."  On the Samba side, I  
ran in interactive mode with debug level 3 and got this at the end of  
the file:

Server exit (normal exit)



When this happens, it appears on the server side that the machine is  
backed up with disk writes.


Can someone tell me how to solve this problem?
