On 2014-07-23, Ubuntu released a security update for Apache. Most of our systems use unattended-upgrades and installed this update automatically. On 2014-07-27, logrotate did its weekly rotation and issued the "reload" command to Apache. Since the new was no longer ABI-compatible with the running Apache, it died with an "undefined symbol" error. This happened on 3 of our systems.

I guess the majority of Apache users are using logrotate too, so it's too late to fix anything for them. But for some users, this may still be a ticking time bomb. I hope the people responsible for the patching are made aware of this mistake and will avoid similar ABI changes in the future.
