An application-level keepalive may be more appropriate.  If
communication happens every 5 to 10 minutes anyway, then a
separate keepalive doesn't seem very useful.  Your application
traffic will let you know when the connection is lost.  Then
you can reconnect and re-send whatever messages you need to.
