Answer 1

This means that probably something went wrong with the string of user_data inside your session-table. It could be that the value of user_data was editted and this can make a serialized string "corrupt".

You should check the documentation on php.net about serialization. About how this process works. http://php.net/manual/en/function.serialize.php
