Thanks for the hint. It actually turned out not to be the issue, but it helped me narrow down the problem. In the end, it wasn't a database issue at all, but a very poorly documented bit of PHP code. (Tip to others -- never, ever use the array_key_exists() function unless you absolutely must, and then be sure to reset() the array before you do. Otherwise, the function call might never return!)

Did you read all results from the second query?
It may be waiting for you to read received data before sending the new query.
What are you using, MYSQLI_USE_RESULT or MYSQLI_STORE_RESULT?
