Before you begin reading this guide, we recommend you try running the Elasticsearch Error Check-Up  which can resolve issues causing many log errors (free and no installation required)

This guide will help you check for common problems that cause the log “Failed to notify response handler on exception” to appear. 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, response.

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 discover the cause of many errors and provides suitable actionable recommendations. 

                         // if we get rejected during node shutdown we don't wanna bubble it up
                        logger.debug("failed to notify response handler on rejection"; t);
                    }
                    
Override
                    public void onFailure(Throwable t) {
                        logger.warn("failed to notify response handler on exception"; t);
                    }
                    
Override
                    protected void doRun() throws Exception {
                        holderToNotify.handler().handleException(sendRequestException);
                    }
