ashb commented on issue #3650: [AIRFLOW-2703] exceptions from scheduler's heartbeat is handled so that scheduler does not crash URL: https://github.com/apache/incubator-airflow/pull/3650#issuecomment-424287008 My major concern is that this would hide serious problems with the connection to the DB (say the DB crashed and isn't running anymore, or the tables are corrupt) - this would then end up creating lots of logs but just keep trying endlessly. Maybe it's worth only allowing _n_ failures in a 60s window, or do you think I am worrying needlessly?
