Apache automatically stops each sunday. Why?

Every sunday at 3 Apache restarts. Problem is: there is a ceritificate on the server with an encrypted private key. Being the password not provided during automatic restart, apache stops and all my websites go down.

I want to stop Apache from restarting every week. How? Here is the apache log at that time. Before [notice] caught SIGTERM, shutting down there's nothing relevant, if you are wondering...

Additional info:

Cron Jobs: /usr/sbin/raid-check this is the only cron job that runs at sunday night (1AM), but if i run it manually nothing happens to Apache...

Solution 1:

Probable cause is the postscript in logrotate script. Thats the script that runs after the logrotation. File should be called /etc/logrotate.d/apache2 or /etc/logrotate.d/httpd (depending od distro) and look something like:

/var/log/httpd/*log {
    missingok
    notifempty
    sharedscripts
    postrotate
        /sbin/service httpd reload > /dev/null 2>/dev/null || true
    endscript
}

Relevant part is 'service httpd reload'. One way to solve it is to just remove last 4 lines (from sharedscripts till endscript, including those two). Also, add copytruncate option, so your logrotate script becomes:

/var/log/httpd/*log {
    copytruncate
    missingok
    notifempty
}

copytruncate will eliminate need for apache restart because it will copy the contents of a log file, and then zero it, so file descriptor will remain the same and apache process won't notice any changes.

To test the logrotate, run:
