Connections to vault still in CLOSE_WAIT status

[Thorsieger]

foreman version : 3.7.0
foreman_vault version : 1.2.0

Hello, we are using foreman_vault to get secret from our vault. But since we upgrade to foreman version 3.7.0 we have connections to vault that do not close, stack and reach the limit of connections. We then only found that restarting foreman close the connections and allow use to regenerate puppet configuration.
