The OOM error in the bug is from overcloud-controller-0, not the undercloud. The overcloud nodes in OVB are still at 6GB. I think it would be reasonable to increase those to 8GB as well. I also noticed that there are 4 neutron-server processes despite having NeutronWorkers: 1 in https://github.com/openstack-infra/tripleo-ci/blob/master/test-environments/worker-config.yaml. If we can get that down to 1, looks like that might save around 270MB. It also looks like there are 2 nova-api workers despite having NovaWorkers: 1. Is that normal? Getting rid of one of them would save around another 140MB. -- -- James Slagle -- __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: [email protected]?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
