Linux TOP, how come totaling the RES column exceeds available physical memory/RAM?
Technically, the RES column shown when using the TOP utility is supposed be the total amount of physical memory a process is using. So how come when I add all the RES used by my processes it seems to exceeds the total amount of RAM installed on the system?
