I want to reload / update my configuration, but I get memory leak warning.

• log4js v2.5.3
• node.js v8.9.0
• macOS v10.13.4

const log4js = require('log4js');
const options = {
	appenders: {
		foo: { type: 'file', filename: 'foo.log' },
	},
	categories: {
		default: { appenders: ['foo'], level: 'info' },
	},
};
const loop = (index = 0) => {
	if (index < 11) {
		log4js.configure(options);
		log4js.shutdown(() => loop(++index));
	}
};
loop();

throw:

(node:19311) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 SIGHUP listeners added. Use emitter.setMaxListeners() to increase limit

Or is there any other way to reload / update configuration?

Thanks
