我在kubernetes中部署了一个redis集群，它带有bitnami/redis集群图。我使用redis cluster npm包从nodejs连接到集群。连接完成后，我试着连续设置上千个键。完成所有的加工时间预计为十分钟。但连接两分钟后，redis的连接就断了。
是否是连接问题，我该怎么办？比如改变配置什么的。
在我的场景或常见场景中，连接丢失的确切原因是什么？
我的代码：

const redis = require('redis');
const redisCluster = require('redis-clustr')
const redisClient = new redisCluster({
    servers: [
    { host: "IP", port: 6379 },
    { host: "IP", port: 6379 }, 
    { host: "IP", port: 6379 },  
    { host: "IP", port: 6379 },
    { host: "IP", port: 6379 }, 
    { host: "IP", port: 6379 } 
     ],
    createClient: (port, host) => {
      return redis.createClient({ 
       port,
       host,
       auth_pass: 'PASSWORD',
     });
   }
});
 <My data processing code to set thousands of keys>
