You could set the session expiration to a long time -- that way, sessions will not be deleted (the number is in seconds).
Set this in /application/config/config.php:
Code:
$config['sess_expiration'] = 7200;
If you set the number to 0, the system will use an expiration of 2 years (which, practically, is like forever).
Or you could set the garbage collection probability to a number below 0. That will prevent sessions from being cleaned up, regardless of session expiration.
You can do so by changing the following line in /system/libraries/Session.php.
Code:
var $gc_probability = 5;
But of course, that could cause problems as the session database will continue to grow.
