 * After the 4.2 update I occasionally get Internal server error. In the error log
   I see this line:
    [Sun Apr 26 00:40:25 2015] [error] [client …] (12)Cannot allocate
   memory: couldn’t create child process: /opt/suphp/sbin/suphp for /home1/webnashr/
   public_html/xmlrpc.php
 * What’s the cause?

 * This looks like WordPress is running out of memory on the web server. Checkout
   the codex link below on how to increase the memory available to WordPress.

 * The memory limit is already 512 M, is there any memory consuming update in the
   new wordpress, especially in xml-rpc file?

 * There shouldn’t be, unless you are using XML-RPC to publish posts on your site
   you may be better off simply deactivating it. The reason it is appearing in your
   error log may be due to malicious attempts of accessing your site. You can disable
   XML-RPC by installing and activating the plugin below.

 * I like to use xml-rpc for updating, but not for pingbacks and trackbacks. Is 
   there a way to just disable those parts?
