NAME
       /proc/pid/oom_score - OOM-killer score

DESCRIPTION
       /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 fac‐
              tors 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.
