Subject Re: [users@httpd] Apache 2.0.52 on Windows 2000 Professional Stops Responding Due to Multiple Simultaneous Requests
Date Tue, 19 Oct 2004 11:48:03 GMT
I am currently using PHP 4.3.9, but have tried all of the following:
    4.3.8
    4.3.5
    4.3.4
    4.3.3
    4.3.2

I am not using any accelerators.  It is a standard Apache configuration with
three virtual hosts and PHP 4.3.9.  It happens in Apache 2.0.52, 51, 40, 49,
and 48.

The request I am talking about (http://webserver/26kb.jpg) doesn't use PHP,
so it shouldn't matter.
