Session table growing after switch to redis

Question

We recently switched our sessions to REDIS and we noticed that our session table in the database is growing and is now 15gb

Here is my config

 <session_save><![CDATA[db]]></session_save>
             <redis_session>
                <host>xxxxx</host>
                <port>6379</port>
                <password>xxxxxxxxxx</password>
                <timeout>2.5</timeout>  
                <persistent></persistent>  
                <db>0</db>
                <compression_threshold>2048</compression_threshold>
                <compression_lib>gzip</compression_lib> 
                <log_level>4</log_level>
                <max_concurrency>6</max_concurrency>
                <break_after_frontend>5</break_after_frontend>  
                <break_after_adminhtml>30</break_after_adminhtml>
                <bot_lifetime>7200</bot_lifetime> 
              </redis_session>

Answer 1

I found that the module Cm_RedisSession.xml was set to false and that this needs to true. I had thought that with the new version of Magento we would use the Mage_ name space and the Cm_ name space was legacy.
