Hey Sean, sorry to have given you bad info here...  I was trying to put 
debug statements in the sshd_conf file (DOH!) which is why that quote 
was there.
This is the current line from /etc/ssh/sshd_conf

Subsystem sftp /usr/lib/openssh/sftp-server

I've cranked up the logging to debug3 and restarted the sshd.
Here:
    http://www.lucii.com/auth.log-piece.txt
is what the log looks like.
(each line starts with:  Aug  4 /time/ master1 sshd[3200]:  )

When I run sftp-server from the command line (as root) it just sits there.
If I run strace /usr/lib/openssh/sftp-server I get a big pile of 
messages - most of which are meaningless to me.  Nothing jumps out and 
says:  HEY!  HERE I AM - I'M THE ERROR YOU'RE LOOKING FOR!

This is the last 20 or so lines of the strace output:

==================================

At this point it's just sitting and waiting.  I terminate with ^C

Does this make any sense to anyone or am I looking in the wrong place :-)

Thanks,
Eric
