title: Memory allocation failed: growing buffer on PHP, SoapClient
body: <p>I am running SOAP client from php and laravel to get a 2mb xml from magento. Sometimes the call succeeds, but mostly it fails with this message:</p>
  
  <pre><code>ErrorException (E_UNKNOWN)
  
  SoapClient::__call(): Memory allocation failed : growing buffer
  </code></pre>
  
  <p>Any ideas how to fix that?
  memory_limit in php.ini is set to 1024M</p>
