--------------------------------------
I have observed this behavior several times over the course of a few
months now.
It seems that any time I update apache2 and related packages, a) Apache
cannot be shutdown cleanly, so all running processes are killed, and b)
libapache2-mod-php5 is removed and never reinstalled. The fact that
libapache2-mod-php5 is never reinstalled causes Apache to fail to start
after the update, due to syntax errors (unrecognized directives) in the
Apache configuration.
The apt-get log transcript follows:

apache2 (2.2.15-1) unstable; urgency=low
* This release adds and enables mod_reqtimeout, which limits the time
Apache waits for a client to send a complete request. This helps to
mitigate against certain denial of service attacks. In case of problems
with slow clients, the timeout values can be adjusted in
/etc/apache2/mods-available/reqtimeout.conf , or the module can be
disabled with "a2dismod reqtimeout".
