Description:
------------
We have got a simple SOAP server and SOAP client implemented on the same web 
server in PHP. When we run few commands via SOAP client only the first command 
results as expected, the next comes with an error.
When we switch to PHP 5.3, everything works fine.

Here is our error log (for PHP 5.4):
[Fri Dec 21 10:13:52 2012] [warn] [client *.*.*.9] (104)Connection reset by peer: 
mod_fcgid: error reading data from FastCGI server
[Fri Dec 21 10:13:52 2012] [error] [client *.*.*.9] Premature end of script 
headers: php.fcgi
[Fri Dec 21 10:13:57 2012] [error] mod_fcgid: process /hosting/cgi-
bin/*/php.fcgi(11985) exit(communication error), get unexpected signal 11

And here are result headers given by SOAP server:
HTTP/1.1 500 Internal Server Error Date: Fri, 21 Dec 2012 09:13:52 GMT Server: 
Apache Accept-Ranges: bytes Content-Length: 1305 Connection: close Content-Type:

Test script:
---------------
//Server
$Server = new SoapServer(NULL, Array('uri' => 'urn:service our_service', 'soap_version' => SOAP_1_2));
$Service = new SOAP_Service($uid);
Server->setObject($Service);
$Server->handle();

//Client
 $Client = new SoapClient(null, array(
        'location'     => 'https://someaddress.com/server.php',
        'uri'          => "urn:service our_service",
        'soap_version' => SOAP_1_2,
        'login'        => '****',
        'password'     => '****',
        'connection_timeout' => 600,
        'exceptions'  => 1,
        'keep_alive'  => 1,
        'trace'       => 1,
    ));

    var_dump($Client->command());
