Should redisConnection be cached and reused?

[y2241]

We are currently reuse the redis connection if it passes redisConnection.isOpen(). It is stored in StatefulRedisConnection<K,V>.
Since we have got a lot of intermittent commandtimeout, I wonder if the cached conection could be the culprit?
What if I get a new connection by calling getRedisClient().connect() everytime I need? Note that the client object is cached.
