MySQL version?

502 is a gateway error, what exactly is generating it, what are the associated error messages from PHP and/or MySQL and/Apache or whatever?

What are the PHP and MySQL timeout settings?

How much RAM does MySQL have? Is the MySQL swapping? What is innodb_buffer_pool_size? What does Explain say about the Update queries? What does Show Engine InnoDB status show during such an update?
