Stories from the internet indicate thatcurl_setopt($ch, CURLOPT_RETURNTRANSFER, true)is broken in for some PHP/cURL versions:

#40831 cURL extension doesnt clear buffer for reused handle

PHP cURL, memory leak when using CURLOPT_RETURNTRANSFER

You can also find stories forDOM:

DOMDocument PHP Memory Leak

PHP/DOMDocument: unset() does not release resources

DOMDocument / Xpath leaking memory during long command line process - any way to deconstruct this class

Create a minimal test case which spots the cause of the leak. I.e. remove the unrelated package (DOM or cURL) from the code.

Then reproduce it with the latest PHP version. If it's still causing the leak,file a bug reportelse use that PHP version.

// cURL opt returntransfer leaks memory, therefore OB instead.
ob_start();
curl_exec($conn);
$responseString = ob_get_clean();
