So I've got a request that always works when I run it in CLI, but using a
browser, it errors out sometimes. It'll error out when I try to run the
request repeatedly, like just refreshing right after it loads. Is there any
setting for apache2 or php.ini that I should set?

Code is here: http://pastebin.com/d67d627b2

SoapApi Class just extends SoapClient by formatting it right like:

function soapGetDHCPLeasesStatus()
{
        //   Get the list of DHCP leases.
        $rc = $this->GetDHCPLeasesStatus(array());

        return $rc;
}
