In the yum update playbook (stroom-ansible-master/stroom/roles/setup/yum_update/tasks/main.yml) it would be better to only reboot if there is a need as per

---
- name: "Do a YUM update on all installed packages"
  become: true
  yum:
    name: "*"
    state: latest
  tags:
    - never # Task won't run unless one of the other tags is set
    - yum_update
  register: upgraded

# The next three tasks will ONLY run if you supply the allow_reboot tag
- name: restart system to reboot to newest kernel
  become: true
  shell: "sleep 5 && reboot"
  async: 1
  poll: 0
  tags:
    - never
    - allow_reboot

  register: reboot
