Following a recent crash, the performance of our 3130 has
fallen significantly. Output from ps aux shows that INIT
is spawning a getty on serial line 2, on which we have an ascii
terminal. After a few seconds, a login process appears for this
line, even though no one is using the terminal. A short while
later, a new getty appears and the cycle repeats endlessly.
I have tried editing /etc/inittab to remove the entry for
serial line 2, and everything returns to normal, as one would expect.
The unwanted processes are spawned at such a rate (about one
every 10 seconds) that the reduction in performance is noticeable.
Anyone have any suggestions as to the probable cause of this
difficulty and how we can resolve it while still using the
serial line?
Any help much appreciated.

I think I have seen something similar when I was trying to you the same port to 'cu' out of the Iris and login into it. With out any more information, I would suggest looking in the IRIS Owner's Guide, Section 7.2 Installing an ASCII Terminal and double check to make sure everything listed there matches with what you have. -- Brent L.

Another thing that can cause this is if the peripheral (I usually see this with modems) is configured to echo characters back to the system. This causes the "login" to get echoed back, the getty thinks someone is logging in, and things get confused.
