I'd suggest cleaning up the bad Ghost directory name at the end of 
your path.

You may want to consider updating your Cygwin DLL to the latest one.

But I doubt either of the above are at least the full explanation for the
problems you're seeing.  However, reading through 
'/usr/share/doc/Cygwin/nfs-server-2.2.47-2.README', I couldn't rule out:

   - Daemons are single-threaded

    The mount and nfs daemons are single-threaded.  This means that
    multiple clients attempting to access NFS exports from a Cygwin
    host may run unto RPC timeout errors.

Could this be the source of your problem?
