Centos Session issues CI 2.2.0

During the development of a new and complex application I ran into the following issue. It seems that the session gets reset when login in.
Simple login structure with a post fo username and password to an authenticator that checks if facebook or google+ are requested - if so the login session seems to go well but when logging in on the CI login_model it does not build up the session data and sends me (the user) back to the login page.

Core system: Centos 6 Dedicated Server Unmanaged
APC and Memcache running for speeding up image and video render processes.

Anyone have a better login script or idea why the session is dropping out?

Whilst we could all take several stabs in the dark at this one, please can you elaborate to allow us to assist further. It is unlikely due to your operating system configuration. What model are you referring to? Can you post your code and any error messages from your log.

Thanks.
