Hi, I'm running Moodle on a Microsoft Windows Server 2008 R2 64-bit server with Apache and PHP (both 32-bit). I was getting Apache crash regularly (e.g. 10 times an hour) with the following error being logged: Faulting application name: httpd.exe, version: 2.2.17.0, time stamp: 0x4cbbe9e8 Faulting module name: php5ts.dll, version: 5.3.5.0, time stamp: 0x4d26013e Exception code: 0xc0000005 Fault offset: 0x0000c699 Faulting process id: 0x335c Faulting application path: C:\Moodle25\server\apache\bin\httpd.exe Faulting module path: C:\Moodle25\server\php\php5ts.dll OK, these versions are pretty old so I upgraded but I'm still getting (presumably) the same error: Faulting application name: httpd.exe, version: 2.4.10.0, time stamp: 0x53c79afa Faulting module name: php5ts.dll, version: 5.5.17.0, time stamp: 0x5418c5a5 Exception code: 0xc0000005 Fault offset: 0x0004b985 Faulting process id: 0xf34 Faulting application path: E:\Server\Apache24\bin\httpd.exe Faulting module path: E:\Server\PHP\php5ts.dll Does anyone have any advice on troubleshooting this? E.g. for getting enough information to log a bug? Moodle is pretty stable, but even if it had a problem I wouldn't expect a crash. Thanks in advance, Leon
