rsync - Feb 2004 - rsync error: some files could not be transferred (code 23) at main.c

I am using rsync to backup a machine with a large number of files, and I
am getting this error.

It would be helpful to know which files this is occuring with, to diagnose
the problem.

Is there a configuration option to rsync (that I may have missed) that
will reveal this info.

Alternatively, is there a source code patch that I could apply to rsync
in order to find out?

Thanks for any help

Follow up to my own posting.

I was running rsync with -v and rsync was having problems chowning (not
transferring) files.  I realise now that the error message applied to this
problem. I found the error message a little confusing, as I was trying to
track down the non-transferred files, while knowing all along about the
chowning problem.
