The BIG-IP system provides an option to use Message Routing virtual servers for MQTT traffic. It uses a different approach to associate a client side and a server side than a standard virtual server. In some instances, a server side is incorrectly handled.
Traffic disrupted while tmm restarts.
-- A Message Routing virtual with MQTT protocol. -- A client attempts to reconnect.
None
When a client attempts to reconnect, and an existing server side connection is used, TMM correctly handles the connection's state and no longer crashes for this reason.
