Description:
------------
When loading a webpage, it occasionally shows "PHP has encountered an Access Violation at 01350AFD" within the body of the page.

Windows 2000 Advanced Server cluster
IIS5 
PHP 4.3.7
Running as ISAPI module 

Server Info: https://secure.bearshare.com/test.php

Display errors is turned off on this server, and errors are being logged to the Event Log.  The main problem here is that an error is being DISPLAYED to the end user.  It should be going to the Event Log instead.

I am reporting this because some other similar bug reports have been closed because the user did not provide enough information.  I am willing to provide plenty of information if I can help to get this bug solved.



Reproduce code:
---------------
Code:  https://secure.bearshare.com/testcode.txt

Expected result:
----------------
Observe at https://secure.bearshare.com/testpage.php

(hit refresh many times to get the error)

The expected result is a normal page of text and graphics.  The actual result is that embedded within the text is an error message "PHP has encountered an Access Violation at 01350AFD" , along with the expected output.

Same problem here.
http://n32k.bud-net.org/0_zombux/pctuning.png

Windows 2003
IIS6
PHP 4.3.7

SMP machine (Dual Xeon, HT disabled)

Application: phpBB. Problem occurs mainly on first loaded page (user not logged in, cookie authentization). Perhaps session related problem.

I have stopped using ISAPI for now, this seems to prevent the bug from appearing.

What extensions are you loading into your PHP?

> What extensions are you loading into your PHP? 

Hi, I've got very similar bug (28954)

I load the following extensions in the php.ini
  php_ldap.dll
  php_gd2.dll

I am not loading any extensions.

Downgrading to 4.3.6 solved that problem for me.

Extensions:
php_gd2.dll

Same problem here, downgrade to 4.3.6 or 4.3.5 doesn't solve it, the only way is to set memory recycling in IIS 6 to very low level such 20 mb for max used memory and 30 for max virtual memory.
This way of work permits to recycle often the working processes and limit PHP access violation but in some cases cause event id 1013 "exceed of time during shut down".

Windows 2003 Enterprise

PHP 4.3.5 / 4.3.6 / 4.3.7

ISAPI

Extensions:
php_gd2.dll

The isapi module is unstable at it's best anyway, use CGI if you need stable environment. (or rather, install Apache..)

I have the same problem with
Windows 2000 Server
IIS5 PHP 4.3.7 & 4.3.8
Running as ISAPI module

PHP info here:
http://lisa.andersenit.dk/serverinfo/info/php/

If i downgrade to PHP 4.3.6 it works fine again, the only change i have made in php.ini from 4.3.6 to 4.3.7 / 4.3.8 is that i have changed from mysql.trace_mode = On to Off

I have this problem on multiple servers.

The php4isapi.dll module has been quite stabe until PHP 4.3.7
