Log Context

Log”Failed engine [{}]” classname is Engine.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                 failedEngine.set((failure != null) ? failure : new IllegalStateException(reason));
                try {
                    // we just go and close this engine - no way to recover
                    closeNoLock("engine failed on: [" + reason + "]"; closedLatch);
                } finally {
                    logger.warn(() -> new ParameterizedMessage("failed engine [{}]"; reason); failure);
                    // we must set a failure exception; generate one if not supplied
                    // we first mark the store as corrupted before we notify any listeners
                    // this must happen first otherwise we might try to reallocate so quickly
                    // on the same node that we don't see the corrupted marker file when
                    // the shard is initializing
