@DavidTurner, I fully agree with you.  
However these are issues:

- FB-\>LS - Invalid version of beats protocol: 71, on simple http connection. Not sure is there any progress on this. Maybe to add [the connectivity timeout](https://discuss.elastic.co/t/filebeat-clients-unable-to-publish-events-to-logstash/378592/31)
- LS - pipeline stops processing, no resource constraints, in jvm.options is default value 1 GB, maybe can be increased, if it is not already set.
- ES - "Connection reset by peer", might be on [OS/network level](https://github.com/elastic/elasticsearch/issues/65213)
