[Mediawiki-l] faulting module php5ts.dll - definitive answer?

[Daniel Barrett]

I'm running MediaWiki 1.9.3 on a dual core Windows 2003 server, 2 GB
RAM, with Apache 2.2.4 and PHP 5.2.1. (Actually it's a VMware virtual
machine.) A few times each day we get this error in the Windows error
log:

  Faulting application httpd.exe, version 2.2.4.0, faulting module
php5ts.dll,
  version 5.2.1.1, fault address 0x0000ae66

and Apache complains:

  [Thu Mar 22 13:21:31 2007] [notice] Parent: child process exited with
status 3221226324 -- Restarting.
  [Thu Mar 22 13:21:32 2007] [notice] Apache/2.2.4 (Win32) mod_ssl/2.2.4

and the user gets a browser error page.

I Googled for this and it's a common problem:

http://issues.apache.org/bugzilla/show_bug.cgi?id=41326
http://www.apachelounge.com/forum/viewtopic.php?p=6502
http://www.apachelounge.com/forum/viewtopic.php?p=4785
http://bugs.php.net/bug.php?id=39603 

but nobody seems to have a workable solution. I have tried:

- increasing the PHP memory_limit in php.ini, but that didn't help.
- Setting Win32DisableAcceptEx as in
http://www.apache.org/dist/httpd/binaries/win32/#xpbug,
in case that was the problem, but that just crashed the server

Any ideas?
