New Comment:
I have been experiencing this issue as well. The server is Windows 2003
with all patches up to date running IIS. PHP version is 5.2.5. I am
running a commandline process using exec(). I have also tried passthru
and shell_exec with the same results. Problem is intermittent and can
not be replicated on demand. The processes themselves can not be killed
until the IIS worker process is killed first although they do complete
all the work they are supposed to. The commands do not die on script
timeout.

If that's any help, I'm using a COM object as a workaround for this
bug, and while it makes this bug appear less frequently, it still
happens, randomly, from time to time.
Here's what i did as a workaround using the exec() function call:
$WshShell = new COM("WScript.Shell");
$OutputFile = "C:\\Temp\\output.txt";
$Command = "cmd /C MyApp.exe > $OutputFile";
$WshShell->Run( $Command, 0, true );
file_get_contents( $OutputFile ) );
unlink( $OutputFile );

Same Problem here with an commandline-script calling other
php-commandline-scripts. It seems to happen more frequently if you have
a lot of exec-calls.

Sorry, I take that last comment back, it still hangs annoyingly
intermittently with shell_exec as well. It's a killer :(

PS: shell_exec() DOES seem to work without hanging on my setup, but
none of the others.

I am experiencing this same problem with PHP 5.2.1 running on IIS as an
ISAPI module on Windows Server 2003 R2 SP2. Intermitently (a handful of
times in a hundred) a process started with exec() will appear to
complete ok but remain running in a zombie state. The IIS worker process
that created the process will not respond to any further requests. I
need to either open a new client browser or kill the worker process.
I get the same result with system, passthru, p_open and proc_open.
