我在使用heroku中的kue连接到Redis来处理多个工作进程时遇到问题。我可以与多个工作人员连接到本地主机上的redis，但在与redis-to-
go连接时似乎断开了。仅当我有多个运行的kue worker /进程时，这才似乎中断。

kue.redis.createClient = function() {
  var client;
  client = redis.createClient(1234, 'tetra.redistogo.com');
  client.auth('xyz');
  return client;
};


jobs = kue.createQueue();
jobs.process("email, 2, function(job, done) {
  console.log("processing email");
  return done(null, null);
});

得到一个错误
