The problem is most likely the one that Frank described. The attempt
to reset the terminal modes is causing the PTY to terminate. Therefore,
the getty driver executes a new login() command on the device.
This would be a bug in the PTY driver. There are many such bugs that
have been fixed with patches from IBM. I'm not sure which version of AIX
you are running, but the IBM AIX APAR database is the place to start.
Search for "pty".
