Hi All, Its not a kernel issue but posting it for better understanding. The output of cat /proc/<pid of program A>/status gives following output: VmPeak: 3141876 kB VmSize: 3141876 kB VmLck: 0 kB VmHWM: 12556 kB VmRSS: 12556 kB VmData: 3140564 kB VmStk: 88 kB VmExe: 4 kB VmLib: 1204 kB VmPTE: 3072 kB What is the meaning of each row? Can anybody explain me? I understand some of the fields but not all (like VmPeak Virtual memory peak limit 3GB here).
