Can you provide the script you are running and the exact error message
you are getting?

Hi
I have a big problem with shell commands execution via PHP.
I have written a very short PHP script ilustrating the problem:
<?php
for($i=0;$i<1000;$i++)
{
exec("test.bat");
}
?>
test.bat is just an empty file.
This script causes about 10 MB memory leak. It can be observed
by usage of performance system monitor. This problems occurs in
all available enviroments:
- IIS Webserver.
- Apache webserver
- PHP command line interpreter
Memory leak is observable only on Windows platform
(tested on Windows XP). On Linux everything works OK.
Does someone know how to solve this problem? Any help appreciated
Best regards
Melmack

I've found exec to be flaky enough on windows that instead I use com to
spawn the new process.
$shell = new COM('WScript.Shell');
$return = $shell->Run($cmd, 0, false);
unset ($shell);
Faster and no leaks ;) Only downside is you have to wrap cross-platform
code with windows detection.
