I have had this (or a very similar) issue before, and i solved it by enabling sessions to use the database.

i.e in the config.php , make sess_use_database to true, i.e

$config['sess_cookie_name']     = 'ci_session';
$config['sess_expiration']      = 7200;
$config['sess_expire_on_close'] = FALSE;
$config['sess_encrypt_cookie']  = FALSE;
$config['sess_use_database']    = TRUE;
$config['sess_table_name']      = 'ci_sessions';
$config['sess_match_ip']         = FALSE;
$config['sess_match_useragent'] = FALSE; //you can try this with TRUE and see if it works
$config['sess_time_to_update']  = 300;

make sure the session table is set in the database as well. if not, here is the sql,

CREATE TABLE IF NOT EXISTS `ci_sessions` (
  `session_id` varchar(40) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT '0',
  `ip_address` varchar(16) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT '0',
  `user_agent` varchar(150) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
  `last_activity` int(10) unsigned NOT NULL DEFAULT '0',
  `user_data` text CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
  `session_data` text NOT NULL,
  PRIMARY KEY (`session_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
