What happens to sincedb if I get this warning?

> [WARN][logstash.outputs.elasticsearch] Attempted to resurrect connection to dead ES instance, but got an error. {:url=\>"[http://localhost:9200/](http://localhost:9200/)", :error\_type=\>LogStash::Outputs::Elasticsearch::HttpClient::Pool::HostUnreachableError, :error=\>"Elasticsearch Unreachable: [[http://localhost:9200/](http://localhost:9200/)][Manticore::SocketException] Connection refused (Connection refused)"}

Does LS discard lines or not if ES is unreachable?

I've LS 5.4 and ES 6.x

Thank you.
