Stacktrace in resque web about redis_failover

[ryanlecompte]

That's interesting. This looks like somehow the underlying redis client is returning nil as a response to an #info command. I've never seen that before. I wonder if this has something to do with the resque-dynamic-queues and it perhaps monkey patching something. Does it happen consistently?

Its repeatable and happens when using the redis multi command:

[1] pry(main)> r = RedisFailover::Client.new(:zkservers => "localhost:2181")    => #<RedisFailover::Client (master: localhost:6379, slaves: none)>
[2] pry(main)> r.multi do
[2] pry(main)*   r.del("foo")
[2] pry(main)*   r.del("bar")
[2] pry(main)* end  
NoMethodError: undefined method `[]' for nil:NilClass
