`RestHighLevelClient` is used to connect to ES 6.4(hosted on AWS) in a spring-boot app. When the app goes idle for some time, and request arrives, then the `RestHighLevelClient` throws `SocketTimeoutException`:

```
[Request processing failed; nested exception is org.springframework.data.elasticsearch.ElasticsearchException: Error while bulk for request: org.elasticsearch.action.bulk.BulkRequest@21511b6c] w

```

_RestHighLevelClient_ is created using:

```
@Bean
  RestHighLevelClient client() {

        ClientConfiguration clientConfiguration = ClientConfiguration.builder()
                .connectedTo(elasticsearchHostAndPort)
                .build();

        return RestClients.create(clientConfiguration).rest();
   }

```

increasing timeout does not help.

Any hints/workarounds?

May be you should give a try to the [Sniffer](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/sniffer.html)?
