Apache Memory Usage Question
I'am just starting using linode and today I moved my wordpress website. After a while a started getting the notifications about memory and CPU load.
Right now the website is under maintenance and I am wondering if these top values (for memory) are normal. To me it seems that apache2 is eating all the memory, how could I discover why?
thank you
