Specifying a Retry Interval for Failed Connections to the MQTT Server
When a connection between Integration Server and the MQTT server fails, Integration Server attempts to re-establish the connection automatically after a 20 second delay. You can configure how long Integration Server waits between attempts to re-establish the connection by changing the value of the watt.server.commonmessaging.connection.retryPeriod parameter.
