When deploying applications using Murano based on Oracle Linux images, the deployment may fail due to the Murano Agent becoming unavailable. This is caused by a loss of the TCP connection from the controller node to the Murano Agent in the virtual machine(s) in the deployment. A loss of the TCP connection may be caused by any action that breaks the TCP connection, for example, by restarting the iptables daemon in an instance.

To resolve this issue, avoid actions that may break a TCP connection.

Workaround: Connect to the virtual machine using SSH, and restart the Murano Agent.

On Oracle Linux 7:

# systemctl restart murano-agent.service

On Oracle Linux 6:

# service murano-agent restart
