samba - Dec 2006 - Broken pipe errors on samba server

I'm running a fairly simple samba server on a sun V440, solaris 9
Samba version:  3.0.10
smbd daemon only

In the server logs I'm getting:

write_socket_data: write failure. Error = Broken pipe
write_socket: Error writing 4 bytes to socket 5: ERRNO = Broken pipe
Error writing 4 bytes to client. -1. (Broken pipe)
setting sec ctx (0, 0) - sec_ctx_stack_ndx = 0
Closing connections
Yielding connection to
Server exit (process_smb: send_smb failed.)
timeout_processing: End of file from client (client has disconnected).


The XP Pro clients report few problems (other than occasional performance)

Wondering if these error messages are an issue and how I might correct them


Here is my smb.conf file:
