|Re: [paho-dev] Retrying message sending in the Java implementation|
The retry while a session is active behaviour was removed from
MQTT 3.1.1 (versus MQTT 3.1). In 3.1.1 the only time retries are
attempted are at reconnection time.
In practice, I found that this behaviour caused more problems than it solved. The usual reason for acks taking a long time would be an overloaded system, which retrying only exacerbated.
