Hello. 

I dont know why but with some tests and verificaton. 

When reconfiguration is stucked. I ran ad hoc with a stuck host or all host: "ansible -i inventoryTest all -m shell -a uptime" then stuck was gone. I can reconfigure.

Hello guys.

I am operating an openstack cluster with kolla but sometimes I cannot reconfigure. It stucked at some hosts(gather fact) and I need to restart docker service on the stucked host to continue. I tried to google but I cannot find the root cause. 

Would you share some experiences on it because my solution causes instances on host to timeout some seconds.

Thank you.
