> We have observed in a production environment cases where an overloaded ActiveMQ broker
stops responding to requests in a timely manner -- connections can be created, but communication
is slow enough to trigger reconnect.
> Unfortunately, the old connections never get cleaned up, leading to resource exhaustion
on the both the clients and the broker.
