Here is how heartbeat works in Dubbo: Heartbeat scheduler will schedule HeartbeatTask in every `heartbeat` time, when being scheduled, HeartbeatTask will internally continue to check the necessity of sending a heartbeat event (only send when it find that the idle interval `>heartbeat`). Consider different combinations of these two intervals: schedule interval and idle interval, we may have a chance of idle for `2*heartbeat` on a wire without any request/response or heartbeat event being sent.
Though the timeout interval in Dubbo is `3*heartbeat`, and `2*heartbeat` idle would not mislead Dubbo to terminate the connection, we may need to increase the frequency of the scheduler to make it more accurate.
