PHP always invokes Two BPEL process Instances

Question

Hello All:
I have a BPEL process that I want to invoke from a PHP form. The problem that I'm having is that every time that I invoke the BPEL process from PHP, two instances of that BPEL process get created and invoked in the BPEL manager.
Has anyone experienced this problem? I know that when I log into the BPEL console and initiate a test instance, I only get one, so my feeling is that it may be PHP. Here is a list of my environments:
BPEL Server Environment
OS Version - Microsoft Windows XP
Oracle SOA Suite v10.1.3.1.0
Oracle BPEL Console v10.1.3.1.0
Client Environment
Server Software - Apache/2.0.55 (Win32)
OS Version - Microsoft Windows XP
PHP Version - 5.1.4
Zend Engine Version - 2.1.0
Here is my PHP code for invoking the BPEL process:
<?php
$wsdl = 'http://localhost:8888/orabpel/default/ChangeCustomerName/1.0/ChangeCustomerName?wsdl';
try {
     $client = new SoapClient($wsdl);
     $return = $client->process(array("cust_account_id"=>167484,"new_cust_name"=>"TESTING>"));
     if ($return->return_code == 'E') {
     echo 'Error: '.$return->return_message;
     } else {
     echo 'Success!';
} catch (SOAPFault $e) {
var_dump($e);
?>
Again the problem is not that I can't invoke a BPEL process or that the BPEL process does not function properly, it is that when I do invoke it from PHP, I get two instances in BPEL.
Thanks,
Ben

If you are using a tool like: soapui.org (Opensource SOAP client tool), and create a soap request, do you get the same behavior. If so, there is an issue in BPEL, otherwise in your PHP environment.
