What happened to SSH?

    Something happened after the last openssh update.  Now every time 
ssh is (re)started, I get this message in my syslog:

Nov 14 08:16:57 lansky sshd[1760]: Server listening on :: port 22.
Nov 14 08:16:57 lansky sshd[1760]: error: Bind to port 22 on 0.0.0.0 
failed: Address already in use.

    That was after a server restart this morning (to boot up the new 
2239 kernel).  The thing is, it does start up, it does run.  And I can 
shut it down completely (service sshd stop) and I can verify that no ssh 
process is running and that there's nothing listening on port 22 ('nmap 
-sS localhost' and by actually trying to connect to port 22 with another 
machine).  Yet when I tell it to start ssh again, it starts, but not 
after complaining with the above message.

    Soooo, inquiring minds want to know.
