Hello,

I am actually working on a PHP extension module writen in C and I have a =
problem I cannot resolve for weeks : it runs perfectly when PHP is =
configured as a CGI script but not when PHP is an Apache module (httpd =
is no more responding after a few requests).

Configuration:
OS: Linux 2.4.20-8 Redhat 9
Server: Apache 2 configured with mpm=3Dprefork
PHP: 4.3.2 or 4.3.3 or PHP 5 (same problem)

Module presentation:
Developped in C, the module.so is placed in the =
/usr/local/lib/php/extensions/no-debug-non-zts-20020429/ directory
All the PHP scripts begin with:
dl('module.so');
I also tried to add extension=3Dmodule.so in the php.ini file and remove =
the dl instruction : same problem

Problem description:
If PHP is compiled with '--enable-force-cgi-redirect' and is a CGI =
script, everything is ok
If PHP is compiled with '--with-apxs2=3D/usr/local/apache2/bin/apxs' and =
is an Apache module, only a few requests are ok (the first one and =
sometime one more). When attempting another request, the httpd is not =
responding and the logs in my application show me that it stopped =
processing during execution of my program. If I changed the C program, =
it will stop at another point as if something was wrong in the memory =
and the problem could appear at any moment...
I have read and read the PHP manual to find out information....

I though about a lot of possibilities :
-problem with C global variable handling (I am not using ZTS),
-problem with Zend variables handling (the C functions are creating and =
updating zval parameters)
-problem with sessions (I tried files and mm with same result)
-bad configuration...
I could give more information if needed.

Anyway, I thank you for the time you will spend reading this email.

Pascal
