That alone, no. "respawning too fast" means that a server, started by
init with the 'respawn' option fails to start properly.
Since it's got the 'respawn' option, init will automatically and
immediately restart the server when it exits, whether successfully or
not. Since this particular server segfaults at startup, it dies
immediately, so init will go in loop trying to restart it all the time.
Since we don't want the system to go down because some server refuses to
start, init will simply stop for five minutes trying to start this server.
Indeed, when the message 'respawning too fast' appears, this can be
anything. In this particular case, though, it's the processor being

No, it doesn't. It stands for an inittab-id (the first field in a line in
inittab). If you do a 'grep "^1\:" /etc/inittab', you will find the

If you really did that, the message will most certainly reappear. What
you probably did was throwing the offending line in comment or out of

Which will probably not help him, since his processor is broken. I
conclude this not only from the fact that init complains about a service
respawning too fast, but also from the fact that random software dumps
core with messages as "Segmentation fault" and "Bus error". When this
happens on m68k, you've got a buggy processor, and that's exactly what
