httpd memory usage

Hello,

I have a question concerning apache memory usage.
I have apache installed on a webserver running Fedora 9 64bit.
The server has 16 GB RAM. When I run the "top" command all the memory is consumed by httpd, there is only 300 MB free. In the column %MEM there are 7 or more httpd pids with a value of 0.1.
How can I tune apache to use less resources? Is it possible that the reason for this behaviour is buggy code from applications?

Best regards,
Obould

Fedora 9 is obsolete and unsupported. Please upgrade to Fedora 16 or some other distro that's more suitable for server use.

Unused memory is wasted memory. The Linux kernel tries to use all of the available 16GB.

That means httpd is using only 0.7% of your memory. It's not "consuming all the memory".
