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.

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?
