MediaWiki:Qp error structured interpretation is too long/qqq

Structured interpretation is serialized string containing scalar value or an associative array stored into database table field. It's purpose is to have measurable, easily processable interpretation result for the particular poll which then can be processed by external tools (via XLS export) or, to be read and processed by next poll interpretation script (data import and in the future maybe an export as well). When the serialized string is too long, it should never be stored, otherwise it will be truncated by DBMS so it cannot be properly unserialized later.
