Dear Jani
There is no problem with 'sample.exe'. I have tested the same for
different exe or even for dos command. It hangs when we are calling the
page at regular interval of time (through Ajax).
There is a problem in the definition of exec() function.
For any further information , feel free to contact me.

What exactly does this "sample.exe" do? It's most likely not any PHP
problem at all anyway, you just call some exe that "hangs" itself..

Description:
------------
Hi! PHP Team
I am facing a problem of apache hang up due to exec() function.
I am using PHP 5.2.5 and Apache 2.2 on MS Window 2000 SP4 & also on MS
Window XP.
The problem is that I have to execute a exe, for which I have use
exec(). Normally it works Fine, but sometime (randomly) it hang up. It
will lock the apache and if we call the same page or any other page of
php having exec(), it hang up at the line where exec() function is used.
If we commented the line having exec(), then the page run & loaded
correctly.
The problem also become critical because there is no error for this.
Also none of the error handling & logging mechanism works.
The only solution to this problem is to restart the Apache.
I am providing you as much as information as possible to catch the
problem correctly.
Reproduce code:
---------------
$exeFilePath = realpath("../sample.exe");
if (eregi("win", PHP_OS))
$command = "\"\"$exeFilePath\" argument1\"";
else
$command = "\"$exeFilePath\" argument1";
$output = null;
$returnVal = null;
$result = exec($command,$output,$returnVal);
if($returnVal !=0)
echo "Error";
else
echo $output[0];
echo "end of the program";
Expected result:
----------------
it will show the output of exe for particular argument.
Actual result:
--------------
Normally it works correctly as expected but sometime the the execution
of the page hang at line "$result = exec($command,$output,$returnVal);"
. After this has happen I am not able to run any script that will use
the exec(). In all scripts apache hangs at exec() function, do not
matter which exe will be called.
