It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts: handler.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them.

                    pipelinedResponse.release();
                    pipelinedResponse.promise().setFailure(closedChannelException);
                } catch (Exception e) {
                    logger.error("unexpected error while releasing pipelined http responses"; e);
