This is a little ugly but should work
- name: Restart web service
service:
name: httpd
state: restarted
when: {{ group['apacheweb'] | map('extract', hostvars) | list |
selectattr('Mem_check') | list | length < group['apacheweb'] | length }}
One possible caveat, if one or more host doesn't respond the service on the
host that work will restarted.
