Thanks for the report. Do you get a segmentation fault logged in /var/log/httpd/error_log? What Apache modules are enabled, can you attach your httpd.conf?
I can see a few messages like, [Tue Aug 10 11:02:15 2004] [notice] child pid 18135 exit signal Segmentation fault (11) I will have to consult with my associate whether they coincide with the crashes. We have created a core dump that it indicates that there was a segmentation fault. I will attach it along with the config files.

I too am experiencing this problem. I think I've tracked it down to PHP. With the php-4.1.2-2.1.8 RPM installed the problem occurs. rpm -e that package (and dependents), restart httpd and the problem goes away. Of course this is perfectly useless if you, like us, are using PHP for anything. I think it is a bug in PHP not Apache. So I've filed bug #132488.
