[nova] [keystone] Default logrotate configuration for apache2

It seems the default logrotate configuration for apache2 log files from vanilla OS installation is to do the following daily: postrotate if invoke-rc.d apache2 status > /dev/null 2>&1; then \ invoke-rc.d apache2 reload > /dev/null 2>&1; \ fi; endscript Sometimes I noticed that not all log entries would show up for the same day after apache2 got reloaded. Also it seems redhat openstack switched its logrotate config to use copytruncate instead of reloading apache2 iirc. Is there some known issues with reloading apache2 daily for logrotate config? Sometimes there are keystone 503 errors, and I am wondering if that's related to the logrotate default config to reload apache2 daily..
