We tested the 5.2 snap on two of our Windows 2003 SP1 servers, and the aforementioned crashes occur with more frequency than with PHP 5.1.4 on the same servers. Previous Comments: ------------------------------------------------------------------------ [2006-05-29 09:22:29] andrej at seznam dot org I came up with exact the same crash analysis, even with the latest PHP snapshot 5.2.0-dev dated May 28 2006 00:17:10: --- Operating System Windows Server 2003 Service Pack 1 Number Of Processors 2 Process ID 8060 Process Image c:\WINDOWS\system32\inetsrv\w3wp.exe System Up-Time 46 day(s) 02:14:04 Process Up-Time 0 day(s) 00:22:07 Thread 15 - System ID 7536 Entry point msvcrt!_endthread+3b Create time 29.5.2006 0:13:40 Time spent in user mode 0 Days 0:0:0.0 Time spent in kernel mode 0 Days 0:0:0.0 Function Arg 1 Arg 2 Arg 3 Source <Unloaded_php5ts.dll>+268810 01626ce0 00000000 00000000 msvcrt!_endthread+ab 0270aa78 00000000 00000000 kernel32!BaseThreadStart+34 77bcb35a 0270aa78 00000000 an access violation exception (0xC0000005) occured on thread 15 when another module attempted to call the following UNLOADED module: php5ts.dll. --- It is weird, that at the moment of crash sometimes there is NO ACTIVITY (= noone is browsing the page). On the other hand, w3swc.exe process consumes too much CPU time, compared to my observations from some time ago, when WebAppPools did not crash. The observed WebAppPool is isolated, I mean, only 1 web uses this pool. ------------------------------------------------------------------------ [2006-05-24 22:12:35] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.2-win32-latest.zip ------------------------------------------------------------------------ [2006-05-19 16:04:44] julien dot jacques at fingerprint dot fr I have exactly the same problem. Since i am on a production server, i can't install MSVC6. (it seems to be replace with MSvisual express2005, which require to remove all sql server prior to 2005. And i can't remove it on production.) I try to add the .pdb to the DebugDiag symbol path but the file doesn't match the dll. Is this because the debug pack is for php5.2.x? Do i have to install php5.2.x-dev? Where can i find the debug pack for php5.1.4? I would be happy to help, but i don't know how to produce the backtrace you require. ------------------------------------------------------------------------ [2006-05-18 17:40:13] jneill at gamedaytv dot com I do not understand these instructions: "When PHP crashes, click Cancel to debug the process. Now MSVC starts up in Debug View. If you don't already see the call stack, go into the View menu and choose Debug Windows → Call Stack." When PHP crashes, we do not see a dialogue box with Cancel as an option, and MSVC does not start up. All that happens is that we get an error in the System Event Log that says something like: --- A process serving application pool 'Site12' terminated unexpectedly. The process id was '3392'. The process exit code was '0xc0000005'. --- So how do I run the debugger? ------------------------------------------------------------------------ [2006-05-17 20:27:21] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
