The QueueStatisticsCollector class manages a hashset called redisques:stats to store statistics for every queue. The items in the hashset do not expire and can only be removed when the corresponding method is called for a specific queue.

We found in our redis database the redisques:stats hset having over 500k entries which caused the used hvals command to take around 400ms.

Many of the queues still in this hash were very old and never deleted.
