我正在使用 http-proxy 将请求转发到特定端口

这是代码：

var httpProxy = require('http-proxy');

options   = {
    hostnameOnly:true,
    router: {
        'appname.nodejs.mydomain.com':'127.0.0.1:8001',
        'otherapp.nodejs.mydomain.com':'127.0.0.1:8002'
    }
}
httpProxy.createServer(options).listen(80);

当我开始它工作得很好但在线用户超过 300 个用户后，出现警告

we have 338 users online.
(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use      emitter.setMaxListeners() to increase limit.

你能给我关于这个问题的任何建议吗？
