      Description

      Hello everyone, i found an particular bug situation

      I have same mqtt producer with high volume traffic. When my application losts tcp connection to mqtt server i have follow connection loop error. This bug is sometime verified because it depend by multiple factors (load machine, load mqtt server, payload, etc)

      I am reading source code and i suppose that the bug is introduced by volatile variable connected (it isn't thread-safe)

      To resolve this bug you must refactoring all MQTTEndpoint connection code.
