Why is Debian Jessie systemd reloading my Apache server every morning?

  • 772

After upgrading a web server from Debian Wheezy to Debian Jessie, the following log entries appear in the system log every morning. The times vary somewhat, but it seems to always happen at approximately the same time (plus/minus maybe 10-15 minutes at most). Nothing similar (that I can recall) happened before the upgrade.

Oct 23 06:25:02 hostname systemd[1]: Reloading LSB: Apache2 web server.
Oct 23 06:25:04 hostname apache2[1545]: Reloading web server: apache2.
Oct 23 06:25:04 hostname systemd[1]: Reloaded LSB: Apache2 web server.

Oct 23 06:29:10 hostname rsyslogd-2359: action 'action 17' resumed (module 'builtin:ompipe') [try http://www.rsyslog.com/e/2359 ]

Looking at the output of service apache2 status:

I'm not sure if I'm looking in the right place, the only part of /run/systemd/generator.late/apache2.service that looks remotely relevant is the mention of the ExecReload command, which is echoed in the service apache2 status output.

Why is systemd reloading the web server with such regularity, despite nobody doing anything on the server, and how do I make it stop?

apache-2.4

  1. Sounds like it might be the post-logrotate reload? If so, it's nothing to worry about as its a non-disruptive reload.
