PHP :: Bug #23455 :: Memory Leak

[2003-05-02 16:11 UTC] adam at planetzerep dot com

I installed Apache 2.0.45 on Windows 2000 SP3, and run apachebench to test... 40,000 requests and no leaks.  I then install PHP 4.3.2RC2 and add these lines to Apache config:

LoadModule php4_module "e:/php4/sapi/php4apache2.dll"
AddType application/x-httpd-php .php

Restart Apache, and then create a PHP file like this:

<?
echo "Test";
?>

Then, re-run apachebench, memory will slowly climb as requests are processed.  More and more memory is used, it doesn't go back down until you restart Apache.

I didn't create a php.ini file -- all settings are at their default.  PHP & Apache are binary versions.

Do you have any PHP modules loaded beside the core?

I am using the PHP win32 binary download, with no php.ini file.  So, I I have not turned on any additional modules.  

Even if I use the recommended php.ini file, and leave all the modules commented out, there is still a memory leak.

This memory leak is not caused by apache "warming up" - I have left apachebench running overnight, and apache will consume all of the memory on the server.

Try the latest cvs snapshot that will be available on May 07, 2003 16:30 GMT.

OK, I downloaded http://snaps.php.net/win32/php4-win32-STABLE-200305071630.zip

It looks like there's still a leak... I ran apachebench:

Apache @ start: 16,988K memory
Apache after 50,000 requests: 30,856K memory
Apache after 100,000 requests: 33,592K memory
Apache after 150,000 requests: 36,336K memory
Apache after 200,000 requests: 39,076K memory

So it seems to be leaking about 56 bytes per request.

Is this still being looked at?

In case anyone is wondering, this bug is fixed in PHP 4.3.9. The Apache 2 SAPI module in older versions was simply leaking whatever sent to it.
