These sound like the same steps I have gone through.  sshd asks for 
root, but it is actually SYSTEM.  This is what I ended up with on 2 
different working systems:

drwxr-xr-x+ 2 SYSTEM Administrators 0 Sep  5 15:53 /var/empty
dr-xr-xr-x+ 2 SYSTEM root 0 Jan 10 12:57 /var/empty

But these did not work for me either when I tried running it from the 
command line (instead of a service).  It had to be owned by the current 
user.  I renamed it and did a mkdir so I could continue debugging. 
Later I put the system one back after renaming the command line version 
in case I have to debug it again later, and now have:

drwxr-xr-x+  2 SYSTEM   root  0 Jan 11 18:06 empty
drwxr-xr-x+  2 VPSAdmin Users 0 Jan 12 09:54 empty.cmdline

The ownership/permissions were the problem on another system I debugged, 
but this box ended up having a totally different problem.  It had a 
program running with so many connections that Window's netstat program 
would not work anymore.  We rebooted and then sshd worked, as well as 
netstat.  The moral of the story is that if netstat isn't working, don't 
bother trying to run sshd.
