Apache - atop showing 100% memory

hello,

I did some investigation before posting.

i noticed that during the time when the httpd consumed 100% memory, only few swap was used.

i got a link on StackOverflow that says its normal as unused memory is wasted memory on Linux.

please let me have your views on this.

ps: I was guessing that before memory becomes 100% used, the swap would be used up first. but this is not the case.

thanks

Please post the full atop and free commands output.
