   Thanks for your detailed explanation @peay 
   
   This makes lot of sense. I think setting  
`AIRFLOW__SCHEDULER__ORPHANED_TASKS_CHECK_INTERVAL` to an appropriate value may 
help reduce these false positives.
   
   In my case, I was connecting to the database through a load balancer and 
load balancer sometimes runs out of ports and drops connection causing the db 
connections from airflow to fail. Some of these connection failures just 
happened to be the heartbeats from these tasks.  Ever since, the db connection 
failures has been fixed, I'm not seeing this error either in my setup. 
   
   Thanks  once again.
