Bug #41943 [Com]: Soap Call causes CPU to go 100%

Edit report at https://bugs.php.net/bug.php?id=41943&edit=1 ID: 41943 Comment by: sblackstone at gmail dot com Reported by: simon at connexon dot com Summary: Soap Call causes CPU to go 100% Status: No Feedback Type: Bug Package: SOAP related Operating System: Windows Server 2003 PHP Version: 5.2.3 Assigned To: dmitry Block user comment: N Private report: N New Comment: I don't have an environment that I can provide a procedure to duplicate this issue, I'm seeing this same problem currently under php 5.3.28 connecting to an IIS server from an OSX dev box. The SOAP server is a bit of a mess and can take up to 130 seconds to respond to queries - in the mean time the process pegs the CPU at 100% utilization. I tried to duplicate this setup with a dummy soap service on an ubuntu box, but I didn't see the same results..

We are using IIS. Perhaps it is the source of the problem... I will be doing more testing on this later this week. Please let me know. Thank you. ------------------------------------------------------------------------ [2007-07-25 06:25:38] dmitry@php.net I am not able to reproduce this. I created a simple client that accesses server over HTTPS: <?php $client = new SoapClient(NULL,array( "location"=> "https://tpl/~dmitry/soap/examples/server4.php", "uri" => "test://")); echo $client->getQuote("ibm"); ?> and server that sleeps for 15 seconds: <?php $quotes = array( "ibm" => 98.42 ); function getQuote($symbol) { global $quotes; sleep(15); return $quotes[$symbol]; } //ob_start("ob_gzhandler"); $server = new SoapServer("stockquote1.wsdl"); $server->addFunction("getQuote"); $server->handle(); ?> and I don't see any CPU load: [dmitry@tpl CGI-DEBUG]$ time sapi/cli/php /home/dmitry/public_html/soap/examples/client8.php 98.42 real 0m15.105s user 0m0.006s sys 0m0.033s I also run the same client on Windows looking into "perfmon" and CPU load was about 0% during waiting. Please provide a COMPLETE reproducable case (client that access external SOAP server, or local client and srver), if you like me to fix the behavior. ------------------------------------------------------------------------ [2007-07-13 12:35:25] simon at connexon dot com How do we do traces? however I was able to isolate the problem. It's SSL that is causing CPU spikes. I ran a soap location with HTTP://, then the CPU would "idle" while it's waiting for a response, however using HTTPS:// the CPU really goes nuts! Is this a problem in the core of PHP itself? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
