Hi I have some huge leaks !!! I have a class define as followed class sforce_webservices extends SOAP_Client while (! $done) { $client = new sforce_webservices($session, $url); $result = $client->query($query); userFunc($result, &$done); } Most of the time I get a malloc error in the curl lib, but I don't know where the leak comes from Ok, I come from a world where you have to free memory by yourself and I don't feel comfortable with garbage collectors. I try also before looping to remove references to $client and $result by doing $client->_reset(); unset($client); $client = NULL; unset($result); $result = NULL; but it's still leaking !!! Did someone noticed the same leak ? Thanks Laurent. Php: 4.3.4 SOAP: 0.8RC2 Curl: 7.10.8
