Subscriptions do not receive data after reconnect

node_redis: 2.7.1
redis: 3.2
platform: Amazon linux
description:
When redis' snapshotting occurs it disconnects the redis client. The client reconnects and resubscribes, however, they no longer receive data. This can be reproduced by issuing a SAVE command via the redis-cli.

JS

const redis = require('redis');
const redisClient = redis.createClient({
  host: config.redisEndpoint,
  port: config.redisPort,
});

redisClient.on('connect', () => {
  console.log('Connected to Redis');
  console.log('subscription_set:', redisClient.subscription_set);
});

redisClient.on('reconnecting', (stats) => {
  console.log('Reconnecting to Redis', stats);
});

redisClient.on('error', (error) => {
  console.log('Failed to connect to Redis: ', error);
});

redisClient.on('subscribe', (channel, count) => { // eslint-disable-line no-unused-vars
  console.log('Subscribed to: ', channel, count);
});

redisClient.on('message', (channel, message) => { // eslint-disable-line no-unused-vars
  console.log('Received from: ', channel, message);
});

redisClient.subscribe('test');

Logs

Initial connect

info: Connected to Redis
info: subscription_set:
info: Subscribed to:  test 1

Issuing a SAVE command in redis-cli

info: Error: Redis connection to 34.213.3.19:6379 failed - read ECONNRESET
info: Reconnecting to Redis delay=983, attempt=4, code=ECONNRESET, errno=ECONNRESET, syscall=connect, address=127.0.0.1, port=6379, total_retry_time=1118, times_connected=1
info: Connected to Redis
info: subscription_set: subscribe_test=test
info: Subscribed to:  test 1

It is at this point that the client will no longer receive any data published to the channel test. If you have any questions or need more info to reproduce please let me know.

Reproduce the report with the supplied node-redis example: subscribe to test, issue SAVE through redis-cli, reconnect, and publish a message. Trace the reconnect and resubscription flow from the client entry points; done means messages arrive on test after the connection is restored, with a regression test covering the sequence.
