codeigniter session expires frequently

[eluser]InsiteFX[/eluser]
If you are using the session table form the CodeIgniter User's Guide it is wrong!

Here is the correct session table, they made a change to the session table on the user_agent

Code:

-- --------------------------------------------------------------

--
-- Table structure for CodeIgniter ci_sessions.
--
DROP TABLE IF EXISTS `ci_sessions`;

CREATE TABLE IF NOT EXISTS  `ci_sessions` (
  `session_id`      varchar(40)    DEFAULT '0'    NOT NULL,
  `ip_address`     varchar(16)    DEFAULT '0'    NOT NULL,
  `user_agent`    varchar(120)                        NOT NULL,
  `last_activity`   int(10)            unsigned        DEFAULT 0  NOT NULL,
  `user_data`      text,
  PRIMARY KEY (`session_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci ;

-- -------------------------------------------------------------
--  `user_data`    text,              COMMENT - maximum length of 65535 characters.
--  `user_data`    mediumtext,  COMMENT - maximum length of 16777215 characters.
--  `user_data`    longtext,       COMMENT - maximum length of 4294967295 characters.

Also if you are running IE make sure the cookie name doe's not have an underscore it!
