> Our metadata DB is in AWS and is a db.4xlarge that mostly looks like its chilling out doing nothing every day. The most action we see is spikes to 350 connections (there's enough RAM for 1750 connections). We're working on weeding out if the spikes are causing issues, but IMHO Airflow should not be falling over in the heartbeats b/c of a first-time missed connection. There should be some intelligent retry logic in the heartbeats... Indeed, we do have some retries in few place, this might not be the one and needs improving. Does this error occur without those network blips / DB connectivity issues? Can someone comments steps to reproduce please -- This is an automated message from the Apache Git Service.
