HI all - I am using Airflow version 1.9.0 and am seeing these random errors in my logs. This causes Airflow to think that the task has failed, even though I can find the process with a ps aux. Any ideas what is causing this? Don't know if this is relevant, but this happens with processes that are fairly long-lived (they poll every minute during the day until it's time for them to run).
