We are getting this error regularly in our production environment. We are building the RestClient using default configurations. ``` public RestClient build() { if (this.failureListener == null) { this.failureListener = new FailureListener(); } CloseableHttpAsyncClient httpClient = this.createHttpClient(); RestClient restClient = new RestClient(httpClient, (long)this.maxRetryTimeout, this.defaultHeaders, this.hosts, this.pathPrefix, this.failureListener); httpClient.start(); return restClient; } ``` Stacktrace: ``` com.repository.exception.RepositoryServicesException: java.lang.RuntimeException: error while performing request at

is there any chance the stack trace is even longer? from a quick peek it looks, as if a HTTP request is timing out while being sent to elasticsearch. Could this happen? ---
