INIT: Id “1” respawning too fast: disabled for 5 minutes

Console error message:

INIT: Id “1” respawning too fast: disabled for 5 minutes

What causes this problem? Apparently, this is due to this line in my /etc/inittab file:

1:2345:respawn:/sbin/getty 38400 tty1

Which says to spawn a terminal on a non existant serial port. You get a respawning too fast error when an inittab line makes no sense. So simptly comment it out:

#1:2345:respawn:/sbin/getty 38400 tty1
