Headers are showing up in apache error log (curl and paypal)

I just noticed in my error logs that whenever I make a request to the PayPal API (using php+curl), some of the returned headers are showing up in my apache error log (not access log). As far as I can tell, this particular request has been filling up my logs since the beginning (few months now) but I just noticed it today for the first time. Now I know that this isn't a big problem by any means, but something I'd be happy to get rid of since it would make troubleshooting other issues easier.

First, here are the error logs:

Even if I make the request using their sample code, the errors still show up. I even have the SSL_VERIFYPEER and SSL_VERIFYHOST curl options turned off in hopes that the ssl (which is valid still) was causing the issues. I've tried other curl requests (not via ssl though) and they don't show up in the error logs.

Can anyone help me pinpoint the issue?

Are you using CURLOPT_CERTINFO? It's described thusly:

TRUE to output SSL certification information to STDERR on secure transfers.

Also check for CURLOPT_VERBOSE, which has to be enabled for CURLOPT_CERTINFO to work in newer PHP versions.

Try using this cURL option:

curl_setopt($ch, CURLOPT_VERBOSE,0);
