CodeIgniter Session Disappear Bug?

Question

I am using CI 1.7.3 and here are my settings:

$config[\'sess_cookie_name\']     = \'ci_session\';
$config[\'sess_expiration\']      = 0;
$config[\'sess_encry

I have the same issue. There's a design flaw in the CodeIgniter sessions library that causes the accidental destruction of sessions when two or more requests are submitted in rapid succession (such as when performing several AJAX requests). I've submitted a bug report that explains in more detail here: https://github.com/EllisLab/CodeIgniter/issues/154

For now, you can implement a workaround by setting sess_use_database = FALSE. Hopefully someone resolves this issue soon.
