we have a cluster of 2 remote memcache servers for session handling but im am not supper happy with the built in handler. Id prefer to have my own PHP level written handler ... unfortunately task gets pushed from release to release and its always bottom priority ; )
Memcached session works stable untill you hit DB peak or something else breaks! then apache threads from cluster build up and you finally exceed connections limit .... things get ugly in that scenario as in PHP script you wont even know that you did not get connection (session is just empty so seems like new visit) nor can you tell how long you want to wait. some further thoughts (its just my thoughts) http://artur.ejsmont.org/blog/content/php-session-in-mysql-vs-memcached but its still pretty damn fast!!!! so we use it : ) >>> any other information regarding what settings / stat values to look >>> for would be helpful. >> my cacti templates if you are new to cacti can be helpful ... full set for a PHP web server http://artur.ejsmont.org/blog/content/palm-v3-bundle-of-php-apache-linux-and-memcached-monitoring-scripts-and-cacti-graphs-apc cheers
