This can happen if you change runlevels - for instance if you've
manually gone to runlevel 3 to install nvidia drivers or something -
Of course sshd is running the whole time, but is told to start up upon
entering the appropriate runlevel. If already running, no harm, but you
would see the message you cited above.
A reboot BTW would serve absolutely no purpose here -
