This morning, a security update for libc has been automatically
deployed on all our servers running 14.04 LTS.
On one of our web servers (only one??) Apache (2.4.7-1ubuntu4.9) has stopped working
after the unattended upgrades of libc6. When Apache received the signal SIGUSR1.
This did not impact any other web server with identical version of all softwares
(aligned with Ansible) ?! -- at least in the beginning of the day...
Later on at 12:52 we did "apachectl graceful" on all our web servers and
all apache servers stopped responding until we restart them with
"service apache2 restart".

This morning I applied the following updates to Ubuntu 12.04
The following packages are currently pending an upgrade:
Apache fails to restart, siting error:

Into file /var/log/apache2/error.log
Looks like I am trying to roll back all those php packages... Which I
see several updates marked Security Update in the changelogs, thus
checking the "security vulnerability" box as rolling back in this case
is such. :-(
