Boot, start X, quit X, run updatedb, reboot... cat /proc/`pidof ntpd`/maps says that it has mmaped only ntpd and few libraries from /lib. I hope that printed values will have some value for you. And btw, ntpd uses some mlock*() call, it has status 'SL' in process list. Do you know how to find what memory it has locked? Jul 31 15:38:13 vana sshd[1303]: Received signal 15; terminating.
