apache restarted/reloaded config by itself automatically, why?
Solution 1:
cron run logrotate, logrotate reload Apache:
/var/log/apache2/*.log {
........
postrotate
if [ -f "`. /etc/apache2/envvars ; echo ${APACHE_PID_FILE:-/var/run/apache2.pid}`" ]; then
/etc/init.d/apache2 reload > /dev/null
fi
endscript
}
