Comment 3 for bug 1298957

We use this option, indeed. See https://github.com/stackforge/fuel-library/blob/master/deployment/puppet/openstack/templates/20-fuel.conf.erb#L30
(and the same for 10-fuel.conf.erb)
1) As you can see, all neutron logs are ensured to be rotated
2) But services cannot be reloaded (no support for SIGHUP yet IceHouse), hence it was decided do not restart them to refresh fd for logfiles and wait for an appropriate SIGHUP support for Openstack services - https://bugs.launchpad.net/oslo/+bug/1276694
3) Thus, in Havana and earlier releases, the issues with log rotation could happen due to the issue mentioned above.
4) The only w/a I can sugest is to ensure forcibly restarting for affected OS services - just put corresponding instructions into the 10-fuel.conf and 20-fuel.conf.

That's why this issue was marked as a duplicate of https://bugs.launchpad.net/fuel/+bug/1276512
