Please try using this snapshot: http://snaps.php.net/php5.3-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Previous Comments: ------------------------------------------------------------------------ [2009-08-19 17:26:55] garre...@php.net I've seen this happen in other languages too. This happens when the pipe between the parent and child fills up, and cmd.exe ends up blocking and creates a race condition. (Windows script host languages trip up on this quickly) in popen_ex() ( in tsrm_win32.c) the pipe is creates with a 2k buffer: if (!str_len || !CreatePipe(&in, &out, &security, 2048L)) { this should probably be significantly larger. I'd certainly go with at least 16k or 32k. (hey, it's only memory :D) as well, the elimination of the unrequired cmd.exe as the immediate child process would eliminate the possibility that *it's* buffer gets overwhelmed too. (which solves bug #43327, and I've passed a patch to Pierre for that.) ------------------------------------------------------------------------ [2009-06-08 16:40:15] alex at bartl dot net Reproducable with PHP 5.2.9-1 on Windows2003 Server with Apache2.2 Workaround with calling session_write_close() before calling exec() confirmed working NOT reproducable with PHP 5.2.1 on Windows 2000 Server with IIS5 anyway, seems to be a duplicate of Bug#44942 ------------------------------------------------------------------------ [2009-05-04 14:56:29] mk1992 at hotmail dot com same problem here, php 5.2.9, w2k3, IIS: shell_exec hanging on production server but not on development server. Can't do downgrade to 5.1.x. ------------------------------------------------------------------------ [2009-04-28 22:52:53] diackne at gmail dot com I have the same issue in windows 2008 web server iis 7 !!! ------------------------------------------------------------------------ [2009-04-22 02:03:38] aliks0905 at gmail dot com I have the same issue as well. I use the exec() function to simultaneously upload files and sometimes cmd.exe freezes and all following uploads fail. I run on a Windows 2003 Server using Apache 2.2.11 and PHP 5.2.9 Looking forward to hearing a solution. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
