Codeigniter session times out very often

You need to do a session_write_close as soon as you no longer need to write to the session data. This will release the lock to let other concurrent ajax call to access the session data in exclusive mode. It helps for performance, because it reduce the waiting time to get a lock on the session. But I don’t think there’s any effect on the session timeout.

Many thanks for that complete information!
