Hi, I am trying to run this rally test on stable/kilo https://github.com/openstack/rally/blob/master/samples/tasks/scenarios/neutron/create_and_delete_routers.json with concurrency 50 and iterations 2000. This test basically cretaes routers and subnets and then calls router-interface-add router-interface-delete And i am running this against 3rd party Nuage plugin. In the NuagePlugin: add_router_interface is something like this: ---------------------------- super().add_router_interface try: some calls to external rest server super().delete_port except: remove_router_interface: ----------------------------------- super().remove_router_interface some calls to external rest server super().create_port() some calls to external rest server If i comment delete_port in the add_router_interface, i am not hitting the db lockout issue. delete_port or any other operations are not within any transaction. So not sure, why this is leading to db lock timeouts in insert to routerport error trace http://paste.openstack.org/show/496626/ Really appreciate any help on this. Thanks, Divya -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-dev/attachments/20160510/13712c0c/attachment.html>
