Logging out nulls sessions, that's how the code works, so unless you have edited Flashchat, that's how yours works.

Sessions (connections) are deleted based on a setting (bolded below) in the config file ;

//Connection processing
'autologoutAfter' => 60, //time of pooling inactivity after which user is considered logged off, seconds
'autocloseAfter' => 900,//time of pooling inactivity after which connection is removed from database, seconds

I can only guess that you have set this very low.
