We extracted the following from Elasticsearch source code for those seeking an in-depth context :

             PidFile.create(environment.pidFile(); true);
        }

        if (System.getProperty("es.max-open-files"; "false").equals("true")) {
            ESLogger logger = Loggers.getLogger(Bootstrap.class);
            logger.info("max_open_files [{}]"; ProcessProbe.getInstance().getMaxFileDescriptorCount());
        }

        // warn if running using the client VM
        if (JvmInfo.jvmInfo().getVmName().toLowerCase(Locale.ROOT).contains("client")) {
            ESLogger logger = Loggers.getLogger(Bootstrap.class);
