Bug #69603 [NEW]: php SoapClient hanging on outbound requests over ~4MB in size

From: photchkiss at vu dot com Operating system: Windows/*nix PHP version: 5.5.24 Package: SOAP related Bug Type: Bug Bug description:php SoapClient hanging on outbound requests over ~4MB in size Description: ------------ I have a wcf service that I am calling from php. This service is used to upload files. I am running into an issue where the request succeeds if the request is smaller than 4MB, but as soon as the request body dips above ~4MB, the soap request hangs. It eventually responds when the remote host forcibly closes the connection and I receive an error saying "Error fetching HTTP headers". I have verified that I can curl the request and build my own SOAP envelope with no problems, so I believe this problem is specific to php's soap client. I have increased my php memory_limit, default_socket_timeout, and post_max_size, with no change in results. I am able to make 4MB+ soap requests using a variety of other technologies as well, but would like to be able to do so using php's native soap client. Please let me know if there are any further questions I can answer to provide more information. -- Edit bug report at https://bugs.php.net/bug.php?id=69603&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69603&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69603&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69603&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69603&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69603&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69603&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69603&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69603&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69603&r=support Expected behavior: https://bugs.php.net/fix.php?id=69603&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69603&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69603&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69603&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69603&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69603&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69603&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69603&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69603&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69603&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69603&r=mysqlcfg
