The problem is that one samba process is handling all the files and
clearcase/NT is keeping the files open.  The default maximum number of
open files under Solaris is 1024.  You can either:

  - crank the limit up by using ulimit before starting samba, or
  - crank down the number of Mnodes on both free lists
    (we have ours set to 800).

I would add "oplocks = False" to your config.  I've also found
complaints in the log file about the socket option IPTOS_LOWDELAY
being unknown; you might want to remove it just to reduce your
log file size.
