Hi, I am seeing the following errors in my ElasticSearch 1.7.6 production.log file when accessing kibana. On the GUI it notes "Courier Fetch: 5 or 70 shards failed" and the following appear in the service logs. I'm happy to provide any other data necessary but I'm very new to ES so if you would please tell me how to get any data requested as well 🙂

You should _really_ upgrade, that version is EOL - [Elastic Product End of Life Dates | Elastic](https://www.elastic.co/support/eol)
Is there more to these errors?
