There was a new setting introduced in PHP 5.3.9 (and was even backported to some earlier PHP versions): max_input_vars. This setting limits the maximum number of variables that can be POSTed (submitted) to the server. Default is set to 1000 but if you have a question with lots of answer options or a survey page with lots and lots of questions/answers this limit might be exceeded. You will need to set this in your PHP configuration file (php.ini).
