I suspect your Zuul layout may not be configured to pass the
OFFLINE_NODE_WHEN_COMPLETE parameter with that job, which should
cause the Jenkins Gearman plugin to atomically offline a node at job
completion without giving Jenkins an opportunity to assign it
another job. For OpenStack Infra we do this with a single_use_node
parameter function in the
modules/openstack_project/files/zuul/openstack_functions.py file in
openstack-infra/config.
