Lost session

[eluser]TSchultz55[/eluser]
Hey all, I'm experiencing the same issues, although I'm not working with any customized code that sets session data. Just enabling the default session functionality like so:

Code:

$config['sess_cookie_name']        = 'ci_session';
$config['sess_expiration']        = 7200;
$config['sess_encrypt_cookie']    = TRUE;
$config['sess_use_database']    = TRUE;
$config['sess_table_name']        = 'ci_sessions';
$config['sess_match_ip']        = FALSE;
$config['sess_match_useragent']    = TRUE;
$config['sess_time_to_update']         = 300;

The odd thing is, if I rapidly hit "Refresh" 10 times, and then go to the DB, there will be 10 unique rows in ci_sessions, each from my IP address. This caught my attention when I noticed there were 153 unique entries in ci_session (all from myself)!

I'm also seeing: "The session cookie data did not contain a valid array. This could be a possible hacking attempt." in my logs.

It's as if CI for some reason completely forgets to check if a session has already been established and just adds it as if it were new.

Not a huge show stopper yet, but kind of annoying. Any thoughts on how to go about fixing this?

Thanks for the help!
