Public bug reported:
Binary package hint: unattended-upgrades
Today, unattended-upgrade upgraded PAM:
# fgrep pam /var/log/dpkg.log |grep upgrade
2011-05-31 06:47:18 upgrade libpam0g 1.1.1-4ubuntu2 1.1.1-4ubuntu2.2
2011-05-31 06:47:20 upgrade libpam-modules 1.1.1-4ubuntu2 1.1.1-4ubuntu2.2
2011-05-31 06:47:24 upgrade libpam-runtime 1.1.1-4ubuntu2 1.1.1-4ubuntu2.2
After this, cron was broken:

user nobody by (uid=0)

Why was cron not being restarted as required by a PAM update? The
solution was to manually restart cron on all affected machines :(
