No experience with AIX, but on our RT running AOS we encounter similar delays - and something even stranger. My understanding of how-it-all-works is that when a session terminates, init (pid 1) catches a signal, updates wtmp, and then spawns a getty. I'm not sure which step is most responsible for the delay, but as you can see there are several places it could occur. We have an even more interesting problem: we're using an auto-baud rate determining getty which apparently DIES after a short period. A lastcomm reveals the following pattern: getty S root tty00 0.03 secs Thu Aug 16 08:41 getty S root tty03 0.03 secs Thu Aug 16 08:41 getty S root tty01 0.06 secs Thu Aug 16 08:41 getty S root tty02 0.03 secs Thu Aug 16 08:41 getty S root ttyc0 0.03 secs Thu Aug 16 08:41 getty S root tty00 0.05 secs Thu Aug 16 08:41 getty S root tty03 0.03 secs Thu Aug 16 08:40 getty S root tty01 0.05 secs Thu Aug 16 08:40 getty S root tty02 0.06 secs Thu Aug 16 08:40 getty S root ttyc0 0.03 secs Thu Aug 16 08:40 getty S root tty00 0.05 secs Thu Aug 16 08:40 getty S root tty03 0.05 secs Thu Aug 16 08:40 getty S root tty01 0.05 secs Thu Aug 16 08:39 getty S root tty02 0.05 secs Thu Aug 16 08:39 getty S root ttyc0 0.05 secs Thu Aug 16 08:39 getty S root tty00 0.06 secs Thu Aug 16 08:39 getty S root tty03 0.05 secs Thu Aug 16 08:39 This is not optimal behaviour IMHO. We're using a Gandalf PACX, and I'm not sure where the fault lies. ttyc0 is not attached, so I'm suspecting that auto-baud is at fault. Anyways, I don't think much can be done about the delay. If you Really Need a login prompt right away, put an exec login at the end of everyone's logout script. ;-) Might even work. ...
