Session timing out intermittently

[eluser]Sumon[/eluser]
would you please try something like

Code:

$this->session->set_userdata('all_session_variables','');
$this->session->set_userdata('all_session_variables','');

and while you check your login use

Code:

if($this->session->userdata('login')=="")
// Redirect to login
else
//Go for further activities..

instead of

Code:

$this->session->sess_destroy();
