WordPress MU

i have mu wordpress installed on an hostgator account and i have big problems. my account was susspended because of this:
"Your site was causing heavy load on the server due to the XMLRPC traffic it generating. Please advice what kind of activity was being done on the account."

how can I avoid this? is any problem if i delete xmlprc.php ? that will resolve my problem?

thanks

WPMU is resource intensive, so shared hosting (like hostgator) is not viable. You need VPS or Dedi ideally.

so there is no another solution?

xmlrpc can be disabled/blocked on a blog by blog basis, Dashboard-->Writing.

Must be a way to do it with an mu-plugin, too. Investigating.

EDIT:
Change first line of xmlrpc.php from true to false
define('XMLRPC_REQUEST', false);

Are you (or your users) using xmlrpc to post to your blogs. If not then it could be ping-back traffic.

Try renaming the xmlrpc.php file. You can then still post using xmlrpc by specifying a different xmlrpc end point if you need to.

Found a hook that works, I think.
mu-plugin to disable xmlrpc:

<?php
function ds_disable_xmlrpc() {
define('XMLRPC_REQUEST', false);
}
add_filter('xmlrpc_methods','ds_disable_xmlrpc');
?>

and where should i paste that code?
thanks
