ID: 44645 Comment by: madhav_2k at yahoo dot com Reported By: gary dot wilson at coull dot biz Status: No Feedback Bug Type: Reproducible crash Operating System: Windows Server 2003 PHP Version: 5.2.5 New Comment:
i am getting the same error as well. "Httpd.exe - Application error The instruction at xxxxxxx referenced memory at xxxxxxx. The memory could not be read" This has completely halted my development and has pretty much rendered PHP on my laptop unusable. I use a Dell Latitude with a Intel Centrino Duo Core processor running Win2k Sp2. Software versions are MySQL 5.1 , Apache webserver 2.2 and Php 5.2.3 This has become a major showstopper and a quick resolution is highly desirable!!

If you are able to provide the information that was originally requested, please do so and change the status of the bug back to "Open". ------------------------------------------------------------------------ [2008-07-05 12:38:11] [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. We also need the script. Is apache a x64 or x86 build (aka runs under 32bit or 64bit OS mode)? If not already done, please use the pdb files (debug pack) so we can see where it crashes (not only which functions). ------------------------------------------------------------------------ [2008-07-05 12:23:26] donald dot lam at live dot com This problem also occurred on my windows 2000 Pro system.

With DB requests prevented, this bug is still repro under high request loads (so it not specifically MySQL / DB connection dependent). Fault address remains at 0x0000926a in php5ts.dll ------------------------------------------------------------------------ [2008-06-03 16:11:02] neil dot smith at coull dot com The following should be a crash dump illustrating the problem. It was generated as per instructions "Generating backtrace without compiler" at http://bugs.php.net/bugs-generating-backtrace-win32.php Configuration : Apache/2.2.3 (Win32) PHP/5.2.5, WinXP SP3 The isue occurred during load testing using JMeter on a script which made moderate MySQL use and medium-heavy XML DOM node creation. Adding memcache caching of DB response resulted in non-repro, which IMO may indicate some involvement of number of DB connections or similar (running script threads between them had around 876 instances of DB connections in TCP 192.168.2.38:3061 192.168.2.15:3306 TIME_WAIT state) ====================== Follows ===================================== Analysis Summary Type Description Recommendation Error WARNING - DebugDiag was not able to locate debug symbols for php5ts.dll, so the information below may be incomplete.
