一次又一次，我们得到这个错误：

{ Error: Redis connection to some-redis-server:6379 failed - read ETIMEDOUT
  at TCP.onStreamRead (internal/stream_base_commons.js:171:27) errno: 'ETIMEDOUT', code: 'ETIMEDOUT', syscall: 'read' }
{ AbortError: Redis connection lost and command aborted. It might have been processed.
    at RedisClient.flush_and_error (/usr/src/app/node_modules/redis/index.js:362:23)

    at TCP._handle.close (net.js:614:12)
  code: 'UNCERTAIN_STATE',
  command: 'GET'
  args: [ 'some-key' ] }

我们使用https://www.npmjs.com/package/redis来访问 redis。设置的一些细节：

• 目前 25GB 的数据存储在 Redis 中
• 写入 = 大约 2MB/秒的速率。
• 最大并发客户端连接数：400

我不知道从哪里真正开始寻找，所以任何帮助将不胜感激。
