Ever since we upgraded our web servers to Windows 2008 R2 we've been getting the following error messages in our event logs:
Faulting application name: w3wp.exe, version: 7.5.7600.16385, time stamp: 0x4a5bd0eb
Faulting module name: ntdll.dll, version: 6.1.7600.16385, time stamp: 0x4a5be02b
Exception code: 0xc0000005
Fault offset: 0x0000000000051da0
Faulting process id: 0xdf4
Faulting application start time: 0x01ca2e4e16aab154
Faulting application path: c:\windows\system32\inetsrv\w3wp.exe
Faulting module path: C:\Windows\SYSTEM32\ntdll.dll
Report Id: 11c920a0-9ab7-11de-9287-000c296aa92b
and at the same time...
A process serving application pool 'www.xxxxxx.co.uk' terminated unexpectedly. The process id was '2328'. The process exit code was '0xc0000005'.
The occurrence seems quite random as it can go a whole day without this message, sometimes happen once or twice a day, and yesterday it happened 10 times in succession causing the app pool for the website to stop (rapid fail protection).
I have reinstalled the server several times, tried both PHP 5.2.10, 5.3.0, 5.3.1dev along with several version of Mysql. I've tried disabling all PHP extensions and a stock version of php.ini, and even the old configuration from our 2008 non-R2 server.
This is not isolated to just one website either. It happens on all PHP based websites hosted by this web server at varying levels of intermittency. What is most strange is that all of these websites worked perfectly on our old Win2008 IIS7.0 server that
was installed in exactly the same way (using the web platform installer).

Thanks for reporting this issue. I will take a look at the dumps and get back to you today.

There is another thread in "IIS7 troubleshooting". Its definitely not a PHP issue. I will follow up on that thread.

Great, 3 years and no fix. R.I.P. IIS, have to go back to Apache :(
