High Cache Miss From Memcache When Storing Sessions

We have been having problems 开发者_JS百科with the memcache server storing sessions data, the cache miss was about 20%, therefore we added in another pool of memcache servers, but now the cache miss rate is up to 50%. Any possible cause or solutions for this problem?

In your php.ini file, the value for session.save_path should not include 127.0.0.1 or localhost.

Use the hostname or LAN ip for the memcached servers.
