Hi Patrick https://activemq.apache.org/components/classic/documentation/networks-of-brokers
In the documentation, there's a configuration for messageTTL in NetworkConnector and the default is 1. I have not verified the documentation myself or have ever used MQTT, so there's a chance that it's outdated or it's not the fix for the issue that you are encountering.
