we have recently installed Redis Cache for our magento based sites.
we 2 websites on our server both using same redis server, our server is based on linux with centos.
the issue we are facing is that redis is consuming quite a lot of RAM, and it is growing by every day.
we have set some values on our magento local.xml file for redis
<redis_session> <host>xxxxxxx</host> <port>xxxx</port> <password></password> <timeout>2.5</timeout> <persistent></persistent> <db>1</db> <compression_threshold>2048</compression_threshold> <compression_lib>gzip</compression_lib> <log_level>1</log_level> <max_concurrency>6</max_concurrency> <break_after_frontend>5</break_after_frontend> <break_after_adminhtml>30</break_after_adminhtml> <first_lifetime>86400</first_lifetime> <bot_first_lifetime>60</bot_first_lifetime> <bot_lifetime>7200</bot_lifetime> <disable_locking>0</disable_locking> <min_lifetime>60</min_lifetime> <max_lifetime>2592000</max_lifetime> <automatic_cleaning_factor>1</automatic_cleaning_factor> </redis_session>
it seems like we do not have an expire set to it, plus there is no memory usage limit either.
i know there are few instruction on internet for setting expire but there is nothing for use with magento in easy way.
all help is apreciated.
