Status: Open
Bug Type: Reproducible crash
Operating System: Windows Server 2003
PHP Version: 5.2.5
New Comment:
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)

Glad someone else found it, I have not gotten any feedback from our
developers, hence php closed this bug. Interesting to see that you get
this on a php connect to MySQL.
Currently, having a wonderful time compiling php 5.2.6 on an CentOS 5.1
x86_64... grrr I hate working at the bleeding edge. Maybe that is why
it is called the bleeding edge because you have to bleed to make it
work.
