  Crashes with WordPress on IIS 8 with WinCache Extensions

  Mar 11, 2013 07:25 PM|LINK

  Hello all,

  recently I set up a web server running Windows Server 2012 Standard Edition.
  This server is hosting one wordpress blog (www.magi-mania.de)

  Unfurtanetly the web site is ran very unstable and logged lots of these events:

  Faulting application name: php-cgi.exe, version: 5.4.9.0, time stamp: 0x50ad2678
  Faulting module name: KERNEL32.DLL, version: 6.2.9200.16384, time stamp: 0x5010a926
  Exception code: 0xc0000005
  Fault offset: 0x00025f9e
  Faulting process id: 0x25f4
  Faulting application start time: 0x01ce1c3e35f7a5b1
  Faulting application path: C:\Program Files (x86)\PHP\v5.4\php-cgi.exe
  Faulting module path: C:\Windows\SYSTEM32\KERNEL32.DLL
  Report Id: af65a468-8831-11e2-93f2-d43d7e0c7eba
  Faulting package full name:
  Faulting package-relative application ID:

  PHP had been installed via Windows Platform installer.

  Then I figured out there might be problems caused by object-cache.php
  So I followed this post:
  http://wordpress.org/extend/plugins/wincache-object-cache-backend/

  After changing this, the site was more reliable, but after about an hour it crashed again and no processing was possible after I did an iisreset.
  
  Has anyone an idea what I can do?

  Without wincache the site is running slower, but stable.

  Best,
  Mark

  Hi,

  From the log above, it seems like that this exception is thrown out when app pool crashes.  In order to resolve your issue, please check whether the worker process in an application pool does not have sufficient permissions to access and write to the following registry key:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<ASP.NETVersion>\Names

  For details, please check the link below:

  Best wishes,

  Hi Catherine,

  My application pool ist set not serving managed code and pipeline mode is clas.
  This has been set by web platfform installer.
  
  I checked this setting for ASP.Net 4.0 and it looks okay. Also I am not using IIS 6 Mode.
  Is there anything else I can check?

  Edit: I am getting now this error:
  So wincache is the definite source for it.

  Faulting application name: php-cgi.exe, version: 5.4.9.0, time stamp: 0x50ad2678
  Faulting module name: php_wincache.dll, version: 1.3.4.0, time stamp: 0x4fd7737e
  Exception code: 0xc0000005
  Fault offset: 0x00005b1e
  Faulting process id: 0x1a50
  Faulting application start time: 0x01ce257fbc1dcd37
  Faulting application path: C:\Program Files (x86)\PHP\v5.4\php-cgi.exe
  Faulting module path: C:\Program Files (x86)\PHP\v5.4\ext\php_wincache.dll
  Report Id: 0e1efe1d-9173-11e2-93f3-d43d7e0c7eba

  Hello,

  I was just wondering, did you ever find a solution to this problem?

  I am having the exact same issue (although on Windows Server 2008 R2).

  Thanks

  Gary

  I am having the same problem, although with Windows Server 2012.  Has anyone found a way to resolve this? It leaves my Application Pool dead and customers are starting to notice.  I'm going to need to setup a monitor to ensure the app pool stays up because the IIS failure settings are not restarting it.

  Hope we can get this error fixed though!

  There seems to be a lot of people having issues with (different versions of) the WinCache extension. My advice is, install and test with a different version if you encounter problems. Even development versions, but always in a test environment.

  You can troubleshoot your PHP/WinCache set up on the command line, just execute php-cgi.exe with the WinCache extension loaded. See http://www.saotn.org/php-54-wincache-on-iis-7-75-80/ for a manual PHP + WinCache installation guide and some troubleshooting options.

  HTH!
