/usr/sbin/getty should be spawned from /etc/inittab. Make sure you have an entry for it in the latter file and ensure that the third field (fields are delimited by the ":" character) is "respawn". The 2nd field relates to the run level in which the command in 4th field is executed.
Killing the PID of the "/usr/sbin/getty console console" process should cause it to respawn. To confirm it has, the PID will be different.
