Bug#869729: apache2: 'service apache2 restart' sometimes stops without restarting
Package: apache2
Version: 2.4.10-10+deb8u10
Severity: normal
Dear Maintainer,
as the subject line says, sometimes running 'service apache2 restart'
fails to restart apache. Instead, it *stops* apache without
restarting it, and fails to give any error message.
In addition, sometimes, *upgrading* the apache2 packages causes the
web server to be stopped without restarting. In fact, I first noticed
this problem when I upgraded to (I think) version 2.4.10-10+deb8u10,
and only noticed a couple hours later that the web server wasn't
running for some reason. So this seems to be a recent change.
It is not easy to reproduce this issue. I just ran 'service apache2
restart' several times in a row, as well as reinstalling the packages
using 'apt-get install --reinstall apache2-bin apache2-utils
apache2-data apache2 apache2-mpm-event', and every time the web server
came back as expected.
(I don't know whether 'systemctl' has the same problem. I manage a
number of heterogeneous systems and use 'service' out of habit.)
This is a heavily customized server with a bunch of weird stuff going
on in its configuration. However, as far as I'm aware, there's
nothing about the apache configuration that *should* cause it to fail
- when I notice that apache is not running, I log in and run 'service
apache2 restart' again, and it works.
