In the past, fluentd supports only UDP heartbeat and it uses async check between fluentd nodes.
So if previous node takes longer time for heartbeat, it doesn't affect elapsed time.
On the other hand, recent fluentd supports TCP heartbeat and it uses sync check via tcp connection.
So if previous node takes longer time, it affects elapsed time for current node and it causes misjudgment.
To avoid the problem, elapsed time calculation should be done after heartbeat.
