In addition to my previous email, I found the following: % ps auwx |grep login root 587 0.0 0.1 1604 1220 p0 Is 5:39AM 0:00.01 login [pam] (login) root 57250 0.0 0.1 1604 1232 p1 Is 7:44AM 0:00.02 login [pam] (login) root 6162 0.0 0.1 1604 1236 p2 Ss 11:08AM 0:00.01 login [pam] (login) Looks like the login process executed via PAM is not exiting (I had only 1 user logged in at this time...), so I guess this is most likely a bug in login? Thanks.
