title: Updated to PHP 7.2 on RHEL and getting frequent cURL errors 28: timed out before SSL handshake
body: <p>I upgraded my RHEL server (yum update) and updated php to 7.2 (ius) and enabled OPCache, now I'm getting intermittent CURL errors for timeouts from my webserver (apache) like:</p>
  
  <pre><code>cURL error 28: timed out before SSL handshake
  </code></pre>
  
  <p>for calls across different hosts.</p>
  
  <p>Any ideas what is causing this or how I can track this bug down?</p>
