Session logout problems

[eluser]chandrajatnika[/eluser]
I have the same problems... this is my config..

Code:

$config['sess_cookie_name']    = 'ci_session';
$config['sess_expiration']    = 7200;
$config['sess_encrypt_cookie']    = FALSE;
$config['sess_use_database']    = TRUE;
$config['sess_table_name']    = 'login_sessions';
$config['sess_match_ip']    = TRUE;
$config['sess_match_useragent']    = TRUE;
$config['sess_time_to_update']     = 1800;

What in the profiler that I should see????
