 [2007-07-12 22:00 UTC] mr_walsh at yahoo dot com
Recently I added a field with a large string to an already stable SOAP call.  This made the SoapClient call hang.  I was able in fact to see from _getLastRequest that if the raw sent XML PHP generates is over 67979 bytes on Mac OSX or something like 11000 bytes on Linux the problem happens every time.  

I ran in the debugger and it makes it nearly certain this is some sort of socket interface problem.

This seems just like bug #29256 but I'm using the very latest php 5.2.3.

Is there some sort of socket configuration I can do as a workaround?

The socket connection is stuck on 'CLOSE_WAIT'
 [2007-07-13 14:19 UTC]
I am not able to reproduce the problem on Linux.
Does the following script hangs for you?

  $client = new SoapClient(NULL,array(
    "location"=> "http://localhost:8080/",
    "uri"     => "test://"));
  echo $client->getQuote(str_repeat('a',65536));

Here's a way to reproduce it...I have a web service server running.  Hit it with this code.  It hangs if you send ~68000 bytes or more (though the limit seemed to be closer to 15000 on a Linux box)

   class Test
   {  public $post;

      public function __construct()
      {  $this->post = str_repeat('a',68536);

   $client = new SOAPClient("",
      array('trace' => 1,
         'soap_version' => SOAP_1_2)

   $t = new Test();

   $resp = $client->Test($t);
   echo strlen($resp->TestResult);

Hi Dimitry:  Is this checked into the 5.x tree, the 6.x tree, or both?

Any way you could tell me which file(s) got touched?  If it's minor I can patch my version?

Thanks again for fixing this!
