Comment 23 for bug 1491576

verified on 7.0 iso #288, steps:

1. deployed cluster with 3 controllers
2. started Rally task 'KeystoneBasic.create_delete_user'
3. scheduled logs rotation at the same time on all controllers (crontab -e; add line '15 9 * * * /etc/cron.daily/logrotate')
4. prepared httpd access log for rotation `mv var/log/apache2/access.log{,.bak}; fallocate -l 500M /var/log/apache2/access.log`

Result - no errors in Rally task (100% success), access log is successfully rotated. Sleep time before reloading apache configuration is different on controllers:

[root@nailgun ~]# runc 'grep sleep /etc/logrotate.d/httpd-prerotate/apache2'
