Hi,
Except mod_rewrite,mod_php,mod_jk no extra module is installed. Apache prefork \
directives are configured as follows (remaining are default). Since I'm serving \
static content through nginx it's only dynamic content that apache serves. MaxClient \
200MaxRequestPerChild 10000
Regards,

You've exprienced the oom-killer (http://linux-mm.org/OOM_Killer). It might not be \
httpd's fault, unless you've misconfigured it to use too much resources in proportion \
to what's available in your system.
Have you changed the configuration or httpd, or installed a new module?
Please provide more information on your setup, otherwise i suspect it would be hard \
to give you any straight answers.
