NAME         top

       /proc/pid/oom_score - OOM-killer score

DESCRIPTION         top

       /proc/pid/oom_score (since Linux 2.6.11)
              This file displays the current score that the kernel gives
              to this process for the purpose of selecting a process for
              the OOM-killer.  A higher score means that the process is
              more likely to be selected by the OOM-killer.  The basis
              for this score is the amount of memory used by the process,
              with increases (+) or decreases (-) for factors including:

              •  whether the process is privileged (-).

              Before Linux 2.6.36 the following factors were also used in
              the calculation of oom_score:

              •  whether the process creates a lot of children using
                 fork(2) (+);

              •  whether the process has been running a long time, or has
                 used a lot of CPU time (-);

              •  whether the process has a low nice value (i.e., > 0)
                 (+); and

              •  whether the process is making direct hardware access
                 (-).

              The oom_score also reflects the adjustment specified by the
              oom_score_adj or oom_adj setting for the process.
