Resque: Redis Timeout Error ...

[JohnBat26]

Hi all.
I have used resque with redis-sentinel.
All works OK, except after long unicorn idle time, resque console begin to raise Redis Timeout error.
If I do service unicorn reload, then Resque console opens correctly.
My redis init configuration:

  Resque.redis = Redis.new(master_name: 'redis-master',
                               sentinels: [
                                   {:host => 'server1', :port => 26379},
                                   {:host => 'server2', :port => 26379}
                               ],
                               failover_reconnect_timeout: 30)

my redis-sentinel.conf

sentinel monitor redis-master 172.21.78.138 6379 2
sentinel down-after-milliseconds redis-master 5000
sentinel failover-timeout redis-master 900000
sentinel can-failover redis-master yes
sentinel parallel-syncs redis-master 1

You probably need to set tcp keepalive
